Answer:
there are only three simple steps (:
Explanation:
1. identify the two points on the line
2. select one to be (x1, y,1) (rise over run) and the other to be (x2, y2)
3. use slope equation to calculate your slope (m=rise/run= y2-y2/x2-x1)
in the equation of a straight line (equation written y=mx+b) the slope is m and b is the y intercept. (where the line crosses the y axis) this is the slope intercept form)
