Which line is parallel to the line y=3x-2?

Question

a) y=3x-8

b) y=1/3x-2

c) y=2x-3

d) y=-3x-5

Answer 1

Arthur,

We take a look at the general equation y = mx + b where m is the slope of the line.

For lines to be parallel, the slope must be equal, therefore, we try to find where m is the same on both equations.

Answer: a) y=3x-8

Answer 2

Hi Arthur, for a line to be parallel with another line, their slopes must be the same. Which of the four answers has a slope of 3?
