Take into account that two lines are parallel if their slopes are equal.

The general form of th equation of a line is:

y = mx + b

where m is the slope and b the y-intercept.

You can notice that for the following lines:

y = -4x - 1

y = -1/4x + 8

the slopes are not equal.

The lines are perpendicular if you verify the following:

m1 = -1/m2
