Coordinate plane: A grid formed by two perpendicular number lines (x-axis and y-axis) used to locate points
x-axis: The horizontal number line on the coordinate plane; left-right direction
y-axis: The vertical number line on the coordinate plane; up-down direction
Origin: The point (0, 0) where the x-axis and y-axis intersect
Ordered pair: Two numbers written as (x, y) that identify a unique point; x comes first, y second
x-coordinate: The first number in an ordered pair; shows horizontal distance from the origin
y-coordinate: The second number in an ordered pair; shows vertical distance from the origin
How to plot (3, 4): Start at origin → move 3 units right along x-axis → move 4 units up → mark the point
Point on the x-axis: Has a y-coordinate of 0; example: (5, 0)
Point on the y-axis: Has an x-coordinate of 0; example: (0, 3)
Distance between (2, 5) and (2, 9): 4 units — same x-coordinate, so subtract y-values: 9 - 5 = 4
Distance between (1, 3) and (6, 3): 5 units — same y-coordinate, so subtract x-values: 6 - 1 = 5
Real-world use of coordinate graphing: Maps, GPS coordinates, video game design, reading line graphs and scatter plots
