Emery Hancock · 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.
