The answer is 370 because you need to work it out.
Basically what I did was look at the first number, 12, and the answer to the equation and saw that 12 x 10 would be 120. And 360 + 10 would be 370.
It fits in perfectly.
12(370 - 360) = 120
370 - 360 = 10
12(10) = 120
So x = 370
We don't really have to put this in slope intercept form; it would clearly end up as
y = -4x + something
so we know the slope is -4.
Answer: C) -4
X+4x = 180
5x = 180
x =180/5
x = 36
answer
