Answer:
G(18,-9)
Step-by-step explanation:
The coordinates of the midpoint of GH are M (8,0) and the coordinates of one endpoint are H(-2, 9). We need to find the coordinates of G. Let G is (x,y).It can be done using mid point formula i.e. [tex](\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})[/tex]
So,
[tex]8=\dfrac{x-2}{2}\ \text{and}\ 0=\dfrac{9+y}{2}\\\\16=x-2\ \text{and}\ y=-9\\\\x=18\ \text{and}\ y=-9[/tex]
Hence, the coordinates of the other point is (18,-9).
