Question

From the given slopes of the lines, identify whether the two lines are parallel, perpendicular, or neither.

Slope 1
6

Slope 2
-6

Answer 1

neither

Explanation:

These two lines will cross (intersect) at one point, but are not perpendicular to one another.

So the correct answer is "neither."

Answer 2

Neither

Explanation:

To be parallel the lines have to have the same slope. In this case the slopes are not the same.

To be perpendicular, the lines have to have negative reciprocal slopes.

For example, if one slope is 6, then its negative reciprocal i (- 1/6). We do not have this also.

So, the lines are no parallel and no perpendicular.
