Best ResponseYou've already chosen the best response.0ok using the points you just used there is an x and y part

Best ResponseYou've already chosen the best response.0so using the points for B which: B= 2, 4 x will be 2 y will be 4

Best ResponseYou've already chosen the best response.0so that will help you fill it in the formula.

Best ResponseYou've already chosen the best response.0Technically the points from B= 2,4 it would be written like this x1=2 y1=4

Best ResponseYou've already chosen the best response.0Do C but instead of using x1 and y1 you have to use x2 and y2 so you can use two other numbers for x and y 2

Best ResponseYou've already chosen the best response.0A = (5, 8) C = (11, 2) x1 y1 x2 y2 slope = Y2Y1 / X2X1 = 28 / 115 = 6/ 11+5 = 6/6 = 1

Best ResponseYou've already chosen the best response.0you just have to continue what you were doing :) this for the slope of BC: m=1−4/1+2 what did you get when you solve that?

Best ResponseYou've already chosen the best response.0m= 3/3 m= 1 Is this right? @Data_LG2

Best ResponseYou've already chosen the best response.0exactly :) your proof will be your solution in solving their slopes and you're done with it
