Answer
$y=3/5x-9/5$
Work Step by Step
We first isolate y by subtracting by 3x on both sides to get that $-5y=9-3x$. We now divide by -5 on both sides to isolate y and get that: $y=3/5x-9/5$. We then plug in the different values of x:
$y=3/5(-1)-9/5=-12/5 \\\\ y=3/5(0)-9/5=-9/5 \\\\ y=3/5(1)-9/5 =-6/5$
