Slopes of Parallel Lines • Two nonvertical lines are parallel iff their slopes are equal
Slopes of Perpendicular Lines • Two nonvertical lines are perpendicular iff the product of their slopes is -1.
What is the equation in slope-intercept form for the line parallel to that contains ( -2, -2) ? Perpendicular?
