Question

Help, I know its not D.)

Answer 1

B.

Explanation:

If two lines are parallel, that means that their slopes are the same.

If they're perpendicular, their slopes would be the negative reciprocal of the other.

For example, if line 1's slope was 5 and line 2 was parallel to it, that means that line 2's slope must be 5 as well. If line 3 was perpendicular to line 1, that meant that line 3's slope would be -1/5.

Answer 2

B

Explanation:

Hey There!

In order for two equations to be parallel they have to have the same slope

The only answer with equation that have the same slope is b

They both have a slope of 2

Hope this helps :)
