This fact can help you check your calculations: if you calculate a slope as being negative, but you can see from the graph that the line is increasing (so the slope must be positive), you know you need to re-do your calculations.

How to calculate (by hand) the slope of a line in a graph: ... Pick two points (X-value, Y-value) that are on the line. The easiest points to pick are points where the line crosses the grid of the graph paper so you don't have to extrapolate the x ... Plug these two points into the following formula to calculate the slope...
