Question

The graph of which of the following will be parallel to the graph of y = 2x – 4?

Answer 1

Any line which is parallel to y=2x-4 will have a slope of 2 (=coefficient of x).
For example, y=5+2x, y=2x-1, y=2x, 2x-y=7, etc.

Answer 2

Well in order for them to be parallel they have to have the same slope
So y = 2x +7
The y intercept has to be different
