A triangle has corners A, B, and C located at #(1 ,3 )#, #(9 ,5 )#, and #(6 ,2 )#, respectively. What are the endpoints and length of the altitude going through corner C?
The endpoints are length
After the equations for the lines from A to B and the line from C perpendicular to line AB are obtained, the intersection point of the two equations—the necessary point D—must be solved simultaneously.
Two-point form line from A(1, 3) to B(9, 5):
Applying the point-slope form
To determine the unknown point D, simultaneously solve the first and second equations.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
