Which lines are perpendicular to the line y-1=1/3 (x+2) check all that apply

y+2=-3 (x-4)

y-5=3 (x+11)

y=-3x - 5/3

y=1/3x-2

3x+y=7

First, third and fifth.

Step-by-step explanation:

Two lines are perpendicular when one's slope is the negative reciprocal of the other's.

The slope of your line is easy to find out: 1/3

Now, a perpendicular line must have a negative reciprocal slope, that is - 3.

Of the five lines given as options, only the first one, the third one and the fifth have a slope of - 3.

For the record, the slope of the second line is + 3 and the slope of the fourth line is + 1/3.
