To find the slope of a line given 2 plotted coordinate points use the following formula
M = y2-y1/x2 - X1
Where the points would be labelled as P1 = (X1,y1) and P2 = (x2,y2). It doesn't matter, usually the larger X and y coordinates are labelled as X2 and y2.
You would take your two points, let's say... (2,1) and (3,2). You would then subtract them using the formula: m=y2-y1/x2-x1 2-1/3-2= 1/1 1/1 is your slope. Hope this helps1
