$m=9; b=-15 $

Work Step by Step

We need to put the equation in the form y=mx+b: $ -2y=6(5-3x) \\\\ -2y=30-18x \\\\ y=9x-15$ 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. -15 is being added to x, so we know that b, the y intercept, is -15.
