$x = -\frac{1}{5} y + 4$

Step-by-step explanation:

The inverse function is a function that reverse a given function.

You can follow this procedure:

The given equation is y = -5x +20

First change the position of the x, because is the variable you need.

-5x+20= y

Now substract 20 in both sides of the equation:

-5x+20-20= y-20

Do the necesary calculations

-5x= y-20

Now divide by -5 both sides of the equation to clear X

$\frac{-5x}{-5} = \frac{(y-20)}{-5}$

simplify:

$x = \frac{(y-20)}{-5}$

$x = \frac{(y)}{-5}-\frac{20}{-5}$

Finally you will get:

$x = -\frac{1}{5}y+4$
