Parallel lines are lines that do not meet no matter how much you extends the lines. Equations of these lines are characterized by having the same slopes. Perpendicular lines are lines that intersect at a point and forms a right angle or an angle of 90 degrees. Therefore, the correct answer from the choices is option 1.
parallel: y = 2x - 7 <span>perpendicular: y = -1/2x + 3</span>
