In a rectangle ABCD, the slope of line AB is 1 and the slope of line BC is 1/2. What is the slope of the altitude to line AD the altitude to line CD.
Thanks in advance.

How are you defining altitude? Normally, I would measure altitude perpendicular to either the axis coordinate, OR perpendicular to a side of the rectangle.
