The two slopes are 2 and 0.5, which multiply to 2*0.5 = 1

This product is NOT -1, so the two lines are NOT perpendicular.

The two slopes aren't equal either, so they are NOT parallel lines.

So the answer is neither

If two lines are perpendicular when
the two gradients are multiplied
together they equal -1 (m1 x m2 = -1)
If two lines are parallel the
gradients will be equal (m1 = m2)
With y = 2x -2 and y = 0.5x, the
lines are neither parallel or perpendicular
