7 and 8 the slope is what is multiplied by x. 9 make y by itself which gives y=3/4x-2. 3/4 is the slope because its multiplied by x. 10 make x by itself to get the x intercept. first subtract 4x. y-4x=-2. then subtract y by both sides.-4x=-2-y. then divide by NEGATIVE 4. after that you will get x intercept form
