Question

100 POINTS! The midpoint of GH is M(4, -3). One endpoint is G(-2, 2). Find the coordinates of endpoint H.

Answer 1

(10, -8)

Explanation:

Answer 2

solution given:

G(x1,y1)=(-2,2)

H(x2,y2)=(x,y)

Mid point M(a,b)=(4,-3)

we have

(a,b)=((x1+x2)/2,(y1+y2)/2)

(4,-3)=((-2+x)/2,(2+y)/2)

comparing corresponding value

4=(-2+x)/2

8+2=x

x=10

again

(2+y)/2=-3

2+y=-6

y=-6-2

y=-8

So coordinates of H is (10,-8).
