Answer:
-8
Step-by-step explanation:
First we need to find the slope of CD.
We know C is (-10, -2)
and we know D is (10,6)
If we use the slope formula, we can see the slope is 

We can see point F is at (6,-4)
We can find the equation of this line by using point slope form, and plugging in F as our point.

To find where E, we need to find the y value when x = -4

It’s a because the total of x and y is 6.80 and the second equation is how much each are and the total being 7.
