Answer

$m=9; b=1/2 $

Work Step by Step

We need to put the equation in the form y=mx+b: $ y-9x=1/2 \\\\ y=9x+1/2$ In order to figure out what the slope is, we must figure out what x is being multiplied by. x is being multiplied by 9, so we know that m, the slope, is 9. We now must figure out what is being added to x. 1/2 is being added to x, so we know that b, the y intercept, is 1/2.
