Question

Item 15

The coordinates of the midpoint of $\overline{GH}$ are $M\left(8,\ 0\right)$ and the coordinates of one endpoint are $H\left(-2,\ 9\right)$ .

The coordinates of the other endpoint are

Answer 1

Explanation:

G(18,-9)

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.

So,
