A) parallel lines
B) perpendicular lines
C) neither

Question

Determine whether the following pairs of equations represent parallel lines, perpendicular lines, or neither of these. ​   ​
A) parallel lines 
B) perpendicular lines 
C) neither

Quizplus · Accepted Answer

The first equation is y = -3x - 2, which has a slope of -3. The second equation is y = 1/3x + 4, which has a slope of 1/3. Since the product of the slopes is -1, the lines are perpendicular.
