m=-1; b=4

Work Step by Step

This equation is in the form y=mx+b. 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, so we know that m, the slope, is -1. We now must figure out what is being added to x. 4 is being added to x, so we know that b, the y intercept, is 4.
