Assume for the graph that the initial equilibrium price and quantity are $10 and 500. If the price increases to $12, then consumer surplus A coordinate plane relates price along the vertical axis to quantity along the horizontal axis, and represents two parallel lines, intersecting a lineThe straight lines labeled S1 and S0 are parallel and intersect the straight line labeled demand at the point (400, 12). The straight line labeled S0 intersects the straight line labeled demand at the point (500, 10). The vertical axis ranges from 0 to 20, in increments of 2, and the values 300, 400, 500, and 1000 are marked along the horizontal axis. Multiple Choice falls by $1,600. falls by $900. increases by $900
