Answer:
(- 7, - 2 )
Step-by-step explanation:
let the coordinates of the endpoint = (x, y ), then
Using the midpoint formula
0.5(5 + x) = - 1 ( multiply both sides by 2 )
5 + x = - 2 ( subtract 5 from both sides )
x = - 7
0.5(2 + y) = 0 ( multiply both sides by 2 )
2 + y = 0 ( subtract 2 from both sides )
y = - 2
The coordinates of the other endpoint are (- 7, - 2 )
