Question 1003848: Determine which two equations represent perpendicular lines.
(a) y = 3/10x – 5
(b) y = 5x – 3/10
(c) y = -1/5x + 3/10
(d) y = 1/5x – 3/10 Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! Perpendicular lines have slope products equal to -1, or the negative reciprocal.
That would be b and c
b slope=5
c slope=(-1/5)
That product is (-1)
