Answer:
Pick two points on the line and determine their coordinates. Determine the difference in y-coordinates of these two points (rise). Determine the difference in x-coordinates for these two points (run). Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope). I cant help you unless I know what coordinates you are wanting to use.
Explanation:
But, we know the formula for slope is y = mx + b. I attached a picture that might be able to help you.
