Coordinates: Points on a grid
A coordinate tells you a point’s location using two numbers.
(x, y)
x = left / right
y = up / down
(0, 0) is the origin (the center)
How to plot a point
- Start at the origin: (0, 0).
- Move x first (right if positive, left if negative).
- Then move y (up if positive, down if negative).
Examples
(3, 2) → 3 right, 2 up
(-4, 1) → 4 left, 1 up
(2, -3) → 2 right, 3 down
(0, -5) → stay on the y-axis, go down 5
(6, 0) → stay on the x-axis, go right 6
Quick tip
x comes first. Always read and write coordinates as (x, y).
Try plotting: (1, 4), (-2, 3), (-3, -1), (0, 2), (4, 0).
