2-5 Distance on the Coordinate Plane

A coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis), used to locate points using ordered pairs (x, y).

Ordered pairs are pairs of numbers used to represent the position of a point on a coordinate plane, written in the form (x, y).

To calculate the distance between two points (x1, y1) and (x2, y2), use the formula: Distance = |y2 - y1| for vertical distance or |x2 - x1| for horizontal distance.

Points are vertically aligned if they have the same x-coordinate, meaning they lie on a vertical line.

Points are horizontally aligned if they have the same y-coordinate, meaning they lie on a horizontal line.
