The answer would be y=-8x-18
The shaded region is above the line so it would be y> so then the equation is y=4x+2 since the graph has a y intercept of 2 and a slope of four
tl;dr the answer is B
500 centimeters I think *sweats nervously*
The function is

.
This means that as we get from 1 to 2, we have the following values:

, and

.
Similarly, if we check x=3, we have

.
We can see that as x changes by 1 (with greater values), y increases by a factor of 12.
Answer: multiply by 12
