Best ResponseYou've already chosen the best response.1that's the equation we need it later but first we have to find slope \[\huge\rm \frac{ y_2 y_1 }{ x_2 x_1 }\] and plug in order pair where x and y are \[\huge\rm (x_1 ,y_1) (x_2 ,y_2) \]

Best ResponseYou've already chosen the best response.1yes right now use that equation plug in m balue m=slope and pick one of order pair replace xand y by their values solve for b

Best ResponseYou've already chosen the best response.1cool and thanks for telling me :=) so \[\huge\rm y = mx+b\] m=4 now you can pick one of order pair where x and y values are (x,y) and then substitute into the equation let's say (1,11) so replace x by 1 y by 11 and m by 4 solve for b

Best ResponseYou've already chosen the best response.1yes b =7 \[\huge\rm y=\color{green}{m}{x}+\color{ReD}{b}\] m=4 b=7 plug in &&& done!
