I looked in the chapter to find a problem like this and there were none. How do you solve this: (4,-3) (3,b) m= -4/5 find b the answer was something like -34/5 ???????? Thanks a lot!!! This question is from textbook Intermediate Algebra through Applications Answer by stanbon(57203)   (Show Source): You can put this solution on YOUR website!(4,-3) (3,b) m= -4/5 find b ----------------- slope = change in y / change in x slope = [b--3]/[3-4] = [b+3]/[-1] Since m= -4/5 and since m is the slope you get the following equation: (b+3)/-1 = -4/5 b+3 = 4/5 b = -3 + 4/5 b = -15/5 + 4/5 b = -11/5 ============== Cheers, Stan H.
