The lines y = -2x + 8 and y = x/2 - 2 meet at (4,0), as shown. What is the area of the triangle formed by these two lines and the line x = -2?
Hint: Check if the triangle is a right triangle by seeing if there are slopes that are negative reciprocals.
- Do you know distance formula?

An alternative method is draw the altitude from C to AB. Then calculate the area, and I got 31.25 as well.
