Often when people see two points, they revert to finding the slope using the algebraic formula m = (y2  y1)/(x2  x1) . This will work, but it's easier from a graph to just count the vertical rise and write it on top of the horizontal run. This slope ratio will be the same between any two points that are on the line. If no points are labeled with coordinates, look for "good points" that is, points where you can be sure that the coordinates are integers.
