Find g(x), where g(x) is the translation 15 units down of f(x)=4x+7. Write your answer in the form mx+b, where m and b are integers.

Question

I got this on ixl review

Answer 1

Since f(x) = 4x + 7 and

g(x) is a translation of 15 units down,

g(x) = f(x) - 15

g(x) = 4x + 7 - 15

g(x) = 4x - 8

This is in the form of y - mx + b, the slope intercept from of a linear equation

where the slope, m, is 4 and the y-intercept is at -8.
