Answer
$m=-3; b=2 $
Work Step by Step
We need to put the equation in the form y=mx+b:
$y-2=-3x \\\\ y=-3x+2$
In order to figure out what the slope is, we must figure out what x is being multiplied by. x is being multiplied by -3, so we know that m, the slope, is -3. We now must figure out what is being added to x. 2 is being added to x, so we know that b, the y intercept, is 2.
