Problem 20 of 7
Determine whether the two lines with slopes 3 and 2 are perpendicular.
Using a hint is okay. It just tells the trainer to give you a little more review.

identify negative reciprocal slopes.
Hidden until you reveal it.
Slopes must allow negative-reciprocal or horizontal/vertical test.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Check whether one slope is zero and the other undefined.
2. Otherwise multiply the slopes or compare negative reciprocals.
3. Conclude perpendicular only if the product is -1.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Reciprocal without sign change as perpendicular.
