PLEASE HELP
A line is perpendicular to another line if m2 = [-1/m1] where m1 is the slope of the original line and m2 is the slope of the perpendicular line. Which of the following equations represents the line that passes through the point (1, –1) and is perpendicular to the line below?

In order for lines to be perpendicular, the slope have to equal -1. $$(m1)(m2)=-1$$

If your choices are already like this: y=mx+b, then m is your slope. Example: |dw:1429054237753:dw|
