To create a SLOPE-INTERCEPT FORM equation, start by creating a T-CHART on your paper and writing y=mx+b on both sides. Then, because it says PARALLEL, that means these equations will have the same slope so you can use the 1.2 given to you and plug it into both equations. Then, use the point (5, 0) which is written as (x, y) and plug it into the first equation. Then, solve for b using Menu 3, 1. Once you find the b, plug it into the second equation.
