Work Step by Step

First objective: write the equation in the form $y=mx+b$; $3x=-2y$ $-2y=3x\qquad/\div(-2)$ $y=\displaystyle \frac{-3}{2}x$ from where we read: slope =$\displaystyle \frac{-3}{2}$, y-intercept = 0. Now, 1. Plot the point $(0,0)$. 2. Using $m=\displaystyle \frac{\Delta y}{\Delta x} =\displaystyle \frac{Rise}{Run}=\frac{-3}{2}$, for a change in x of $2$, y changes by $-3$, which leads us to the point $(0+2,0-3)=(2,-3)$ We now have two points... . Draw a straight line through $(0,0)$ and $(2,-3)$.
