Please answer! Thank you in advanced

Answer 1

Answer: D

Explanation:

To solve this problem, let's go through each pair to see if they are perpendicular lines.

A. Incorrect

These are parallel lines. We know this because they have the same slope and different y-intercept.

B. Incorrect

These are not perpendicular lines. The slope is
`-(1)/(m)`. The slope of the pair doesn't match this property.

----------------------------------------------------------------------------------------------------

C. Incorrect

These are not perpendicular lines. The slope is
`-(1)/(m)`. The slope of the pair doesn't match this property.

----------------------------------------------------------------------------------------------------

D. Correct

These are perpendicular lines. The slope is
`-(1)/(m)`. The slope of the pair matches this property.

----------------------------------------------------------------------------------------------------

E. Incorrect

These are not perpendicular lines. You can see that y=5 and x=5. The slope is
`-(1)/(m)`. The slope of the pair doesn't match this property.
