y=mx+b\medskip\\\begin{cases}-2=3m+b\\2=b\end{cases}\Leftrightarrow\begin{cases}-2=3m+2\\b=2\end{cases}\Leftrightarrow\begin{cases}m=-(4)/(3)\\b=2\end{cases}\medskip\\y=-(4)/(3)x+2

The slope of this line is the difference of the y values divided by the difference of the x values. Solving this give 4/-3. Then, you already know the b in y = mx+b, which is 2, because you already have the value (0, 2). So, the answer is y =
-(4)/(3)x + 2
