Line l has a slope of −3. The line through which of the following pair of points is perpendicular to l? i will give brainliest for the answer A. (−4,−3),(−3,−6)
B. (−18,−1),(−3,0)
C. (−6,−4),(−3,−3)
D. (−2,−3),(−3,−6)

D

Step-by-step explanation:

ALWAYS REMEMBER THIS EQUATION:

Find the slope of answer A

1.

 2. This answer is not perpendicular to "l" because it is equal to -3. (Even if it has a different y-intercept, it will just be parallel, not perpendicular.)

Find the slope of answer B

1.

 2. This answer is not perpendicular to "l".

Find the slope of answer C

1.

 2. This answer is not perpendicular to "l".

Find the slope of answer D

1.

 2. This answer is perpendicular to "l" because 3 is the inverse of -3.

$12. that is my answer.
