SOLUTION: Determine which two equations represent perpendicular lines. (a) y = 5/3x � 3 (b) y = 3x � 5/3 (c) y = -1/3x + 5/3 (d) y = 1/3x

Question 45984: Determine which two equations represent perpendicular lines.
(a) y = 5/3x � 3
(b) y = 3x � 5/3
(c) y = -1/3x + 5/3
(d) y = 1/3x

Answer by Earlsdon(6294) (Show Source): You can put this solution on YOUR website!
Remember that the slopes of perpendicular lines are the negative reciprocal of each other.
Since all of the possible answers are in the slope-intercept form y = mx+b, you can compare the slopes of the answers to find two slopes that are negative reciprocals.
b) The slope is 3
c) The slope is , the negative reciprocal of 3
