Question 417862

{{{y = 5x + 4}}}

Begin by solving for {{{x}}}:

{{{y - 4 = 5x + 4 - 4}}}

{{{y - 4 = 5x}}}

{{{(y - 4)/5 = x}}}

Now interchange {{{x}}} and {{{y}}}:

{{{(x - 4)/5 = y}}}

If you want it to write in the standard form({{{y = mx + b}}}) then just write it like this:

{{{(1/5)x - 4/5 = y}}}

so, {{{y = (1/5)x - 4/5}}}...is your inverse
