Question

What is an equation of the line that passes through the point

(−4,−6) and is perpendicular to the line 2x−y=6?

Answer 1

Explanation:

-y = -2x + 6

y = 2x - 6

perp. -1/2

y + 6 = -1/2(x + 4)

y + 6 = -1/2x - 2

y = -1/2x - 8

Answer 2

Explanation:

The slope of the given line is 2

The negative reciprocal of it is -½

y--6=-½(x--4)

y+6=-½(x+4)

2y+12=-x-4

2y=-x-4-12

2y=-x-16

y=-½x-8
