Question

What are the intercepts of f(x)=5x-45

Answer 1

The y-intercept of f(x) = 5x - 45 would be -45, as that is what is represented in the equation. The way to find the x-intercept would be to solve the equation when f(x) = 0.

     0 = 5x - 45
+ 45         + 45

   45 = 5x
    /5     /5
     9 = x

And there we have it.
The intercepts of f(x) = 5x - 45 are as follows:

y-intercept = -45
x-intercept = 9

Hope that helped =)
