Best ResponseYou've already chosen the best response.0(5  7)/(5  7) (5 + 7)(5 + 7) 12/12 1 So slope = 1

Best ResponseYou've already chosen the best response.0Then you use this formula (y  y.) = slope(x  x.) My "." usually have a subscript of 1 but I don't know how to make that happen. The y. and the x. are the x's and y's that you you know. You pick one point and use those values. I am going to use the (5,5) point

Best ResponseYou've already chosen the best response.0(y  5) = 1(x  5) y  5 = x  5 add 5 to both sides y = x This is your answer
