Question

The midpoint of GH is M(6,-4). One endpoint is (8.-2). Find the coordinates of endpoint H.​

Answer 1

(4,10)

Explanation:

midpoint = (6,4)

one point = (8,-2)

other point = (x,y)

(x + 8)/2 = 6

x + 8 = 6*2

x + 8 = 12

x = 12 - 8

x = 4

=================

(y - 2)/2 = 4

y - 2 = 4*2

y -2 = 8

y = 8 + 2

y = 10
