Question

Which equation represents a line which is parallel to the line y=2x-5

1. 2x+y=8
2.x+2y=-4
3.y-2x=-8
4.x-2y=6

Answer 1

3. y-2x=-8

Explanation:

Answer 2

3

Explanation:

when two lines are parallel, they have the same slope

you can find slop by changing the equation to slope intercept form (y=mx+b), m being the slope

slopes:

1. -2

2. -1/2

3. 2

4. 1/2
