Line d has a slope of 3/2. Line e has a slope of -2/3. Are line d and line e parallel or perpendicular?

We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel. Unlike parallel lines, perpendicular lines do intersect
