If the coordinates of point e are (-4, y), what is the value of
у?

-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

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is symmetric about the line y = 120,000.
