Y intercept is (0,-0.7) and X intercept is (-1.2 ,0)
10 x 10 = 100
20 + 20 + 20 + 20 +20 = 100
4 x 25 = 100
I don't see a b or an m in this function, but generally, a linear function is of the form ax+b. The b in this equation (not sure if it is the same as your b), controls the shift of the function. Lower b by 3, the graph shifts down by 3.
So unless there is a minus sign before b, it has to be lowered by 3. (If there is a minus sign, it has to be increased by 3).
Answer:
3
