Question

Write the equation of the line that is parallel to the line y = -3x + 12 and passes through the point (-1, 6).

Answer 1

y=-3x-7 I believe.

Answer 2

y=3x-9

Answer 3

Sorry. The 2nd one is right.

Answer 4

Put it into point slope form. Y-y1=m(x-x1)

y-6=-3(x+1)

Solve it out. We know the slope is -3 because parallel lines have the same slope.

Answer 5

wouldn't it be 1/3 ?

Answer 6

Parallel lines have the same slope, perpendicular have opposite reciprocal slopes. You're thinking of perpendicular, but in this case the slope of a parallel line would be -3.

Answer 7

ohhh okay. i got it.
