Answer:

Step-by-step explanation:
Angle EFB = 180 - 147 = 33 (Angles on a straight line add up to 180 degrees)
Angle FEB = 180 - 4x (Angles on a straight line add up to 180 degrees)
Since the angles in a triangle add up to 180 degrees ,

Remove brackets:

Add/Subtract:

Subtract 213 from both sides:


Divide both sides by -3:

Answer:
y=-7x -2
Step-by-step explanation:
use formula to find the equation when you know slope and a point
it is: y-y1 = m(x-x1)
plug in values
y-(-30) = -7(x-4)
y+30 = -7x + 28
- 30 from both sides
y = -7x -2
