Petra needs to find the equation of a line through (–2, 3) that is parallel to the line represented by y = 2x– 4. Which equation best represents Petra's equation?

The answer is y=2x+7. First put it in point slope form then solve it into slopeintercept form. Use the same slope because having parallel lines means the same slope.
