Plot the intercepts to graph the equation

Prism m and pyramid n have the same base area and the same height. cylinder p and prism q have the same height and the same base perimeter. cone z has the same base area as cylinder y, but its height is three times the height of cylinder y. the figures and have the same volume.

What is the y-intercept of the line with the equation 3x + 4y = 12?
