Parallel & Perpendicular Lines
Parallel or Perpendicular?
Example 4
Determine whether the following lines are parallel, perpendicular or neither. Line 1: 3x + 4y = 2 Line 2 : 3x - 6y = 5
Step 1. Rewrite the equations in slope-intercept form and determine the slope of each.
Step 2. Compare the slopes.
The slopes are not the same or opposite reciprocals of each other,
so the lines are neither parallel nor perpendicular.
