Answer
$m=-1/2; b=0 $
Work Step by Step
We need to put the equation in the form y=mx+b:
$y+1/2x=0 \\\\ y=-1/2x$
In order to figure out what the slope is, we must figure out what x is being multiplied by. x is being multiplied by -1/2, so we know that m, the slope, is -1/2. We now must figure out what is being added to x. Nothing is being added to x, so we know that b, the y intercept, is 0.
