4. We are building a thin triangular plate with variable density. The triangle has vertices (0, 0), (2,0), and (2,4), and the density (in g/cm) at each point in the triangle is given by the formula 8(x, y) = 5+4x-6y + y. At what point(s) is the density of the triangle the least or the greatest? What is the density at these points? (Use either method to check for extrema along curves.)
