Answer:

Step-by-step explanation:
The given inequality is

Add 4 to both sides of the first inequality and subtract 5 from both sides of the second inequality.

We simplify to get:

Divide through the first inequality by 4 and the second by 9.

The midpoint is (-2, -6). You need to find the mean of x coordinate and the y coordinate.
slope=y2-y1/x2-x1
5-2/3-2
denominator will show 3-2
