C. y = –6x + 4

D. y = –6x – 4

Answer:

D. y = –6x – 4

Step-by-step explanation:

Find the slope of the original line and use the point-slope formula  y − y 1 = m ( x − x 1 )  to find the line parallel to  y = − 6 x + 2 .

y = − 6 x − 4                 PARALLEL

Find the negative reciprocal of the slope of the original line and use the point-slope formula  y − y 1 = m ( x − x 1 )  to find the line perpendicular to  y = − 6 x + 2 .

y = 1 /6 x + 13/ 6            PERPENDICULAR
