Question

Which of the following gives and equation of a line that passes through the point (6/5,-19/5) and is parallel to the line that passes through the origin and point (-2,-12)?

Answer 1

A. y=6x-11

Explanation:

1) Calculate slope

(0,0) (-2,-12)

(-12-0)/(-2-0) = 6

The parallel equation will have same slope(of 6)

2) plug in point (6/5, -19/5)

y=6x+b

-19/5=6(6/5)+b

b=-19/5-36/5=-55/5 = -11

3) equation

A. y=6x-11
