Exercise 13 Page 247

To graph the equation $5x-7=2(x+1),$ we will create two functions out of the left- and right-hand sides of the equation. The $x\text{-}$coordinate where the graphs of these functions intersect is the solution to our equation. Since one of the given equations is not in slope-intercept form, let's rewrite it so that it will be easier to identify its slope and $y\text{-}$intercept.
