Answer by Fombitz(32388) (Show Source): You can put this solution on YOUR website!
Perpendicular lines have slopes that are negative reciprocals of each other.
In other words,
The product of the slopes is -1.
All of your equations are in slope-intercept form.
and
From your 4 choices, the answer is B and C since
Graphing the equations, you see they are perpendicular.
