lines a and b are perpendicular. The slope of line a is given. What is the slope of line b?
-1/2
Perpendicular lines have slopes that are negative reciprocals of each other, so change the slopes sign and flip it upside down.
:
Line a has a slope of -1/2
so line b has a slope of 2/1=2
Happy Calculating!!!
