Which lines are perpendicular to the line y – 1 = one-third(x 2)? check all that apply. y 2 = –3(x – 4) y − 5 = 3(x 11) y = -3x – five-thirds y = one-thirdx – 2 3x y = 7

Answer:

a and c

Step-by-step explanation:

y - 1 = 1/3(x - 2)

y = 1/3x - 4/3

Only the slope matters in this problem. If the original equation has a slope of 1/3, you need to use the reciprocal and negate it. So the perpendicular slope would be -3.

 a. y 2 = –3(x – 4)

b. y − 5 = 3(x 11)

c. y = -3x – five-thirds

d. y = one-thirdx – 2 3x y = 7

So a and c are perpendicular to y - 1 = 1/3(x - 2)
