In general, P(n, r) denotes the product n * (n - 1) * ... * (n - r + 1) of the r consecutive integers the largest being n. So, for example, P(7, 3) = 7 * 6 * 5, P(7, 1) = 7... and, for any integer n, P(n, 0) = 1.

When multiplying two different points on a graph, you simply multiply the x-coordinates together, as well as the y-coordinates, giving you a new (x,y) point. P(8,2)*P(5,4)=P(?,?) -------------- x-coordinates: 8 and 5, y-coordinates: 2 and 4 -------------- Therefore... P(?,?)=P(8*5,2*4) =P(40,8)07/19/19
