Parallel & Perpendicular Lines
Parallel or Perpendicular?
Example 6
Determine whether the lines are parallel, perpendicular or neither. Line 1: 7y + 1 = 7xLine 2: x + 5 = y .
Step 1. Rewrite the equations in slope-intercept form and determine the slope of each.
Step 2. Compare the slopes.
The slopes are the same and the intercepts are different, so the lines are parallel.
