Explanation:
Coordinates are always written as (x, y) — go along the corridor (x-axis, horizontal) first, then up or down the stairs (y-axis, vertical). In all four quadrants, left of the origin (0, 0) gives a negative x-coordinate and below the origin gives a negative y-coordinate.
To find the midpoint of a line segment joining (x1, y1) and (x2, y2), average the x-coordinates and average the y-coordinates: Midpoint = (x1 + x22, y1 + y22).
Example 1: A(−3, 2), B(3, 2) and C(3, −2) are three corners of rectangle ABCD. Find the coordinates of D.
Example 2: Find the coordinates of the midpoint M of the line joining P(−4, 7) and Q(6, −1).
