Best ResponseYou've already chosen the best response.1subtract your points and stack y/x for slope: m then pick either point (Px,Py) and construct the equation: y = mx mPx + Py

Best ResponseYou've already chosen the best response.1(1,4) ( 2,2)  3,6; slope = y/x = 6/3 = 2 y = 2x +2(1)+4 = 2x 2+4 = 2x + 2

Best ResponseYou've already chosen the best response.1we can test it out to BE sure: y = 2x + 2 ; try out (1,4) 4 1  4 = 2 + 2 ; thats good y = 2x + 2 ; try out (2,2) 2 2  2 = 4+2 thats good as well

Best ResponseYou've already chosen the best response.1the formula is just a compact way to write the steps, you still have to do the steps. P(x1 , y1) Q(x2 , y2)  (x1x2, y1y2); slope = y/x = (y1y2)/(x1x2) but even that is misleading because it doesnt matter which point you start with

Best ResponseYou've already chosen the best response.1your not keeping track of your numbers to well, which happems to me when i try this horizontal conflagerations. I always do a vertical format so that i dont mix up numbers

Best ResponseYou've already chosen the best response.1if we do "the formula" m = (42)/(12) = 6/3 = 2 or m = (24)/(21) = 6/3 = 2
