Answer to Problem 9CE
The lines are neither parallel nor perpendicular.
Explanation of Solution
Given:
The slope of two lines are
Calculation:
Two lines are parallel when they have same slope.
Two lines are perpendicular when product of there slope is
Since, the slope of two lines are neither equal nor the product of slopes is
Therefore, the lines are neither parallel nor perpendicular.
