PLEASE HELP ASAP
Determine whether the pair of lines are parallel, perpendicular, or neither.

Answer 1

Perpendicular

Explanation:

First, you need to make it so both equations look the same.

I would subtract 3x on both sides of the second equation in order to isolate y:

y = -3x + 2

Now that we have both functions, we can look at their slopes:

First slope = 1/3

Second slope = -3

Two lines are parallel if their slopes are the same, and perpendicular if their slopes are reciprocals of each other.

1/3 and -3 are reciprocals of each other, and therefore these lines are perpendicular.
