Review Lesson 5-6: Find the slope of a line perpendicular to the graph of each equation.

slope of a perpendicular line: 3
slope of a perpendicular line: 1/4
slope of a perpendicular line: -\frac{1}{3}
slope of a perpendicular line: -3
slope of a perpendicular line: 4

y = 3x
y = -\frac{1}{4}x
\frac{1}{3}x - y = 2
