to find a perpendicular line, the slope for equation 1 and equation 2, when multiplied equal -1.

bee_see · Answer

m=slope. (m1)(m2)=-1

bee_see · Answer

To find the slope of the graph, use rise/run (in this case you are going to go "down" instead of "rise"). You begin at the y-intercept. Check where the line crosses a point on the graph.
