GOODMAN Group TitleBest ResponseYou've already chosen the best response.0
y=mx+b You have m(slope)= 3/7 And you have (x, y) (9,2) x=9 and Y=2 We need to find b. So we plug all this information in to the equation y=mx+b 2=(3/7)(9)+b Solve that and you will get b. Once you have b, plug it in to the equation, along with the slope.
