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).
Using slope intercept form, you can come p with the equation, <u>s=150m</u> where 150 is the savings per month and you were not given a starting point which would be y.
