The Cartesian plane, named after the French mathematician René Descartes, is the foundation of coordinate geometry. It's a two-dimensional plane defined by a horizontal x-axis and a vertical y-axis, intersecting at the origin (0,0). Imagine it as a vast, empty canvas where every point has a unique address, or coordinates, represented by an ordered pair (x, y).
Divided into four quadrants by the axes, the Cartesian plane is like a bustling city, each quadrant with its unique 'residents'. In the first quadrant (top-right), both x and y are positive, much like a vibrant, lively neighbourhood. The second quadrant (top-left) has a negative x-axis, think of it as a quieter, more reserved area. The third and fourth quadrants follow the same logic, with the third being the 'suburban' area (negative y-axis) and the fourth, the 'industrial' zone (both axes are negative).
A grid system, a network of horizontal and vertical lines, helps us locate points precisely on the Cartesian plane. It's like a map of Singapore, with major roads (axes) and smaller lanes (grid lines) helping us navigate. Each intersection on the grid is a point with a unique coordinate, just like how every MRT station has a distinct name and location.
The scale on the axes determines the size of each unit, much like the distance between MRT stations. A smaller unit means more precise plotting, like having more stations between two points. In Singapore's secondary 3 math syllabus, students learn to work with different scales and units, understanding how they affect the size and position of shapes on the plane.
Finally, plotting points is like placing landmarks on our map. Given coordinates, we mark the point by moving 'steps' along the axes. For instance, to plot (3, 2), we take 3 steps right (along the x-axis) and 2 steps up (along the y-axis). It's like following simple directions to reach a specific location in Singapore, like 'Take the MRT 3 stops and then walk 2 blocks north'."

Before we start verifying, let's ensure we've got our plotting down pat. In Singapore's Secondary 3 Math Syllabus, you'll learn that:
Interesting Fact: The origin (0, 0) is like the heart of the coordinate plane. It's the only point where both the x and y coordinates are zero!
**
**
Alright, adventurer! Now that you've got your points plotted, it's time to check if you're on the right track. Here's how:
History Lesson: You might be wondering, where did these quadrants come from? Well, they were first introduced by René Descartes (remember our Indiana Jones of math?). He divided the plane into four regions to make plotting and understanding points easier.
**
**
What if you're given a point like (3, -2)? Is it in the first quadrant or the fourth? Let's verify!
Starting from the origin (0, 0), move 3 units to the right for the x-coordinate, then 2 units down for the y-coordinate. You'll end up in the fourth quadrant! So, (3, -2) is indeed a point in the fourth quadrant.
Remember, verifying your plotted points is like checking your GPS. It helps you stay on track and ensures you reach your destination accurately.

Wow, you've come a long way! You've learned about coordinate geometry, plotting points, and, most importantly, how to verify their accuracy. You're now ready to tackle Singapore's Secondary 3 Math Syllabus like a champ!
So, the next time you're navigating the coordinate plane, don't be afraid to double-check your points. After all, even the smallest mistake can lead you to the wrong destination. Happy plotting, and here's to many more math adventures!
" width="100%" height="480">Coordinate geometry checklist: Verifying the accuracy of plotted points**
**Imagine you're in a vast, empty white room, armed with a red pen and an infinite roll of graph paper. You're given coordinates (1, 2). Where do you plot your point? Easy peasy, right? Wrong! Let's dive into the world of coordinate geometry and explore the common pitfalls Singapore's secondary 1 and 3 students face when plotting points, and how to avoid them.
You're not in a white room, but a Cartesian plane, named after René Descartes, the French philosopher who developed the coordinate system. It's like a giant, invisible grid that stretches out in all directions, with two number lines (the x-axis and y-axis) intersecting at a point called the origin (0, 0).
**Fun Fact:** Descartes wasn't the first to use coordinates. That honour goes to the ancient Greeks, but it was Descartes who popularised the method we use today.
When plotting points, remember that the first number in the coordinate pair represents the horizontal distance from the origin (the x-coordinate), and the second number represents the vertical distance (the y-coordinate). So, (3, 4) is not the same as (4, 3). The first point is three units to the right and four units up; the second point is four units to the right and three units up.
**Interesting Fact:** This rule isn't universal. In some systems, like the polar coordinate system, the order is different. But for now, let's stick to Cartesian.
Positive x-values move you east (to the right), negative x-values move you west (to the left), positive y-values move you north (up), and negative y-values move you south (down). It's like navigating with a compass, but instead of degrees, you're using coordinates.
**History Lesson:** The first recorded use of coordinates to locate points on a plane was in 1637 by Descartes, in his La Géométrie.
**What if** you could plot points with your eyes closed? Well, you can! After practising a bit, you'll be able to visualise the grid and plot points without even looking at your paper. It's like having a mental map of the Cartesian plane.
So, the next time you're plotting points, remember: x comes first, north is up, and always start from the bottom left. With these tips, you'll be navigating the Cartesian plane like a pro. Now, go forth and conquer those coordinates!
Understand the four quadrants of the coordinate plane and the signs of coordinates in each. Plot points using their ordered pairs (x, y).
Write the equation of a line in slope-intercept form (y = mx + b) and standard form (Ax + By = C) using given points or slope and y-intercept.
Calculate the midpoint of a line segment given two points. Apply the distance formula to find the distance between two points on the coordinate plane.
Calculate the slope (m) of a line given two points. Use the slope formula: m = (y2 - y1) / (x2 - x1).
Plot points and connect them with a straight line to graph a linear equation in the coordinate plane. Check for accurate graphing by substituting x and y values back into the equation.
