Question

a line segment has an endpoint at (-3,9), and its midpoint is at (3,3). what is the ordered pair for the other endpoint if the line segment.

Answer 1

(9, -3)

Explanation:

The coordinates of the midpoint are the averages of the coordinates of the endpoints.

For the x coordinates:

3 = (-3 + x) / 2

x = 9

For the y coordinates:

3 = (9 + y) / 2

y = -3

The other endpoint is at (9, -3)
