Y = -2x - 4
y = 2x + 4

-2x - 4 = 2x + 4
-2x - 2x = 4 + 4
-4x = 8
x = -8/4
x = -2

y = 2x + 4
y = 2(-2) + 4
y = -4 + 4
y = 0

solution (-2,0)

Answer:

x = 8 units, measure of angle AFE = 60 degrees, measure of angle CFD = 60 degrees

Step-by-step explanation:

Finding x:

You know all three of the given measures add up to 180 because they are on the same side of the line. Write an equation and solve for x.

6x + 2 + 8x + 6 + 7x + 4 = 180

21x = 168 --> x = 8

Angle AFE:

Substitute the value of x in the given measure.

7x + 4 = 7*8 + 4 = 56 + 4 = 60

Measure of angle CFD:

Angle AFE is it's vertical angle, so their measures (60 degrees) are equal.
