lines a and b are perpendicular. The slope of line a is given. What is the slope of line b? I am assuming the slope of a is 3.
Perpendicular lines have slopes that are negative reciprocals of each other. Change the sign and stand the slope on its head.
a has a slope of 3 or 3/1
Then b has a slope of -1/3
Happy Calculating!!!
