For 15 to 20, change the equation from y=mx+b into mx-y=-b Example: 15) y=-5x+2 into -2=-5x-y or 2=5x+y For 21-29, the numbers in the parenthesis are coordinates (x, y) so uh the equation y=mx+b plug in the m that is given and x and y and then solve for b to complete the equation Ex: 21) (-8,3) m=2 Y=mx+b 3=2(3)+b 3=6+b -3=b So y=2x-3 Do the same to the others
