Question

Which equation represents a line which is parallel to the line y=3x+1

Answer 1

2y=6x+4

y=3x+2. That has a slope of 3 and is parallel to y=3x. All the others have a slope of something else.

If the slope is -3x, then 6x+2y=4 and 2y=-6x+4 and y=-3x+2

6x+2y=4 is the answer for the question y=- 3x
