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.

P_ex4-1v2

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.
