subtract your points and stack y/x for slope: m then pick either point (Px,Py) and construct the equation: y = mx mPx + Py

The answer that I came up is y=3x+1. The teacher says its y=2x+2

(1,4) ( 2,2)  3,6; slope = y/x = 6/3 = 2 y = 2x +2(1)+4 = 2x 2+4 = 2x + 2

isn't the formula y1y2/x1x2

we 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

the 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

your 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

if we do "the formula" m = (42)/(12) = 6/3 = 2 or m = (24)/(21) = 6/3 = 2
