Two-point perspective has one set of lines parallel to the picture plane and two sets oblique to it. Parallel lines oblique to the picture plane converge to a vanishing point, which means that this set-up will require two vanishing points. Walls in 2-point perspective, converging toward two vanishing points.
They intersect a t a certain point. They intersect at the price where the amount producers are willing and able to supply converges with the amount consumers are willing and able to purchase. This point of convergence is called the equilibrium price. Theoretically it is where supply and demand meet and prices settle. If suppliers ignore demand, and continue to produce units and price them too high, they will not be purchased. Instead they will sit in the warehouse.
