How do you graph 7r-15=r+27

This is a vertical line

Step-by-step explanation:

Lets go easy on this by solving the equation 7r-15=r+27, you get 6r = 42

from where you obtain that r=7

Since you want to graph this equation (r=7), think of it as x=7, this means that no matter what value has the 'y' variable, x always will be x=7
