To find inverse:
Step 1:Rewrite h(x) as "y"
Step 2: Swap/Swicth the places of x and y
Step 3: Solve for the "new" y
Step 4: Rewrite y as "h-1(x)"
 
step 1: h(x) = -3x + 6
               y = -3x + 6
 
step 2:     x = -3y + 6
 
step 3:     x - 6 = -3y
                  -3      -3
                x - 6 = y
                 -3
step 4:  h-1(x)= x - 6
                          -3

Thank you for your help. How would this look on a graph? I do not know how to graph this.
Because the actual question is which graph represents the inverse of h(x)=-3x+6 but I thought I could figure it out if I just found out what the inverse was.

Hi Trish!
The inverse of h(x) is just an equation of a line. Here it is written in different form: h-1(x) = -1/3x+2. It's the y = mx+ b form of a line. The y-intercept is 2 and the slope m= -1/3. hope that clears it up. Sometimes it's hard to see answers when written in different form. Wished I could show you graph.
