Answer:
y = 30x + 20
Step-by-step explanation:
y = mx + b
find b
b=20
find m
m=30

is in the 3rd quadrant... (It is also 210 degrees)
To find the reference angle (which is the distance to the x-axis)

(or 30 degrees)
sin
Create the equation:
250-13x
Plug in 4 for the equation and solve:
250-13(4)
250-52
198
The answer is C. 198
The correct answer is x^2-4x-12
