By applying the midpoint formula, the other endpoint is equal to (-1, -5).
How to determine the other endpoint?
In order to determine the midpoint of a line segment with two (2) endpoints, we would add each point together and divide by two (2).
Midpoint on x-coordinate is given by:
(7 + x)/2 = 3
7 + x = 6
x = 6 - 7
x = -1.
Midpoint on y-coordinate is given by:
(1 + y)/2 = -2
1 + y = -4
y = -4 - 1
y = -5.
Therefore, the other endpoint is (-1, -5).
