To find the slope of the line, you first need to know two points
((x%5B1%5D,y%5B1%5D) and (x%5B2%5D,y%5B2%5D) ) that the line is going through, and
calculate the change in y+ over the change in x, or the
rise+over the run.

The change is the difference between the two+coordinates.
So
if the y-coordinate of a point goes from y%5B1%5D+ to y%5B2%5D, the
change in these numbers is y%5B2%5D+-+y%5B1%5D+.
If the x-coordinate changes from x%5B1%5D+ to x%5B2%5D, then the
change is x%5B2%5D+-+x%5B1%5D+.

- to calculate the slope we use this formula:

m+=+%28y%5B2%5D+-+y%5B1%5D%29%2F+%28x%5B2%5D+-+x%5B1%5D%29+=+rise+%2F+run+ where m is the slope
