Answer:
2
Step-by-step explanation:
To find the slope of the graphed line, you take two points. I have chosen (0, 4) and (8, 0)
The formula of a slope is (y value of second point
value of first point) divided by (x value of second point
value of first point):

------------------------------------------------------------------------
The slope for a perpendicular line is 2.
The answer to this is -76
The answer and work is in the SS below
Angle 6 - 30
Angle 5 - 73
Angle 1 - 37
Angle 2 - 52
Angle 4 - 63
Angle 3 - 128
Mma can see that 2.09 is closer to 2 than 2.36.
