N lines.
Which lines are perpendicular to the line y-1=1/3 (x+2)? Check all that apply.
O y + 2 =-3(x – 4)
y-5= 3(x + 11)
y=-3x - 5
y = 3x-2
3x + y = 7

Perpendicular lines have negative reciprocals. This means that if you multiply the slopes of both lines, the product will be a -1.

In your given point-slope equation, the slope is 1/3. Therefore, the negative reciprocal of 1/3 must be -3.

Out of the given options:

y + 2 = -3(x — 4)
y = -3x - 5

are the linear equations that are perpendicular to y — 1 = 1/3(x + 2).

Therefore, the correct answers are Options 1 and 3.
