Front

If two lines are parallel, what can be said about their slopes?

Back

Their slopes are the same.

Front

Are the lines y = 4x + 2 and y = (-1/4)x + 12 perpendicular?

Back

YES

Front

If two lines are perpendicular to each other, what can be said about their slopes?

Back

Their slopes are inverse (opposite) reciprocals of each other.
