Question

The lines given by the equations y=4x and y=0.25x are

Answer 1

They are not parallel because the slopes are different (slope of 4 and slope of 0.25)

Neither are they perpendicular. If they were then m1*m2  ( the product of their slopes) would be -1 ). The product of these slopes = 4*0.25 = 1)

So choice  A is the correct one.
