Which graph correctly compares the volumes, V, of rectangular pyramids with different heights, h, when their bases all have the dimensions of 4 feet by 6 feet? (Recall that the volume of a rectangular pyramid can be found using the formula, V = one-third B h, where V is the volume, B is the area of the base, and h is the height.)
On a coordinate plane, the x-axis is labeled Height of Pyramid (feet) and the y-axis is labeled Volume of Pyramid (cubic feet). A line goes through points (1, 8) and (2, 16).
