Step 3
Compare the slopes of the two equations.
Step 4
Compare the decimal form of one slope with the negative reciprocal of the other slope. If they are equal, then the lines are perpendicular. If the they are not equal, then the lines are not perpendicular.
Step 5
The equations are perpendicular because the slopes of the two lines are negative reciprocals.
Perpendicular
