Answer:
( 3,-5)
Step-by-step explanation:
To find the midpoint add the two end point coordinates and divide by two
Let G be ( x,y)
The midpoint of GH is (2,2)
( x+1) /2 = 2
Multiply by 2
x+1 = 4
Subtract 1
x+1-1 = 4-1
x=3
( y+9) /2 = 2
Multiply by 2
y+9 = 4
Subtract 9
y+9-9 = 4-9
y = -5
The coordinates of G is ( 3,-5)
