Answer:y=4x -7
Step-by-step explanation:
The slope intercept form is: y= mx + b
Y+3 = 4(x-1) step one distribute 4
Y+3= 4x - 4 step two subtract 3 from both sides
Y=4x -7
Since angles EFA, AFB, and BFC lie on a straight line, then they must add up to 180° (angle sum of a straight line)
So, 7x + 4 + 8x + 6 + 6x + 2 = 180
21x + 12 = 180
21x = 168
x = 8
