Find the other endpoint if one endpoint is at (-5,-6) and the midpoint is at (1,1) a - (1,1) b - (8,7) c - (-7,-8) d - (7,8)

The coordinates of the other points are (7,8)

Step-by-step explanation:

Mathematically, we have the midpoint formula as;

(x,y) = (x1 + x2)/2 , (y1 + y2)/2

(1,1) = (-5 + x2)/2 , (-6 + y2)/2

-5 + x2 = 2(1)

x2 = 2 + 5 = 7

(-6 + y2) = 2(1)

-6 + y2 = 2

y2 = 2 + 6

y2 = 8

The coordinates of the other points are (7,8)
