Question

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

Answer 1

The slope of the given line is 1/3.

The perpendiculars all have the negative reciprocal slope, -3.

A. y + 2 = -3(x-4)

Yes, slope -3.

B. y - 5 = 3(x+11)

No, slope 3.

C. y = -3x - 5/3

Yes, slope -3.

D. y = 1/3  x - 2

No, that's slope 1/3.

E. 3x + y = 7

That's

y = -3x + 7

Another slope -3, Yes.
