Proving Relationships of Parallel and Perpendicular Lines

Proving Relationships of Parallel and Perpendicular Lines 1.11 - Solution

arrow_back Return to Proving Relationships of Parallel and Perpendicular Lines

Parallel lines have the same slope but different intercept. Perpendicular lines have slopes that are opposite reciprocals of one another. Therefore, to determine if the lines are parallel, perpendicular, or neither, we first need to find their slopes using the Slope Formula.

Line Points Slope Simplified Slope

These lines have different slopes so they can't be parallel. We can determine if they are perpendicular by multiplying the slopes. Since the product of the slopes equals the lines are perpendicular.
