Question

What is perpendicular to -1/-7

Answer 1

7/1

Explanation:

To find a perpendicular line you must take the slope and use its opposite reciprocal.

Let's say you have a slope of 3/4. The perpendicular line would be -3/4 because it is the opposite reciprocal.

Answer 2

Perpendicular is opposite reciprocal so it is just -7 since it is -1/-7 that is really 1/7 and the opposite of positive is negative and the reciprocal of 1/7 is 7
