Answer:

G = (-1.5,1.5)

Step-by-step explanation:

Given

M = (-7,5)

A = (6,5)

T = (4,-2)

H = (-9,-2)

Required

Determine the coordinate of G

From the complete question, G is at the intersection of MT and AH.

So, G is calculated using midpoint formula

G = \frac{1}{2}(x_1 + x_2, y_1 + y_2)

For MT:

M = (-7,5)      T = (4,-2)

G = \frac{1}{2}(-7 + 4, 5 -2)

G = \frac{1}{2}(-3, 3)

Open bracket

G = (-1.5,1.5)

To show that G = (-1.5,1.5)

We have:

A = (6,5)       H = (-9,-2)

G = \frac{1}{2}(x_1 + x_2, y_1 + y_2)

G =\frac{1}{2}(6-9,5-2)

G = \frac{1}{2}(-3, 3)

Open bracket

G = (-1.5,1.5)

Hence, the coordinates of G is:

G = (-1.5,1.5)
