Q10. The height of a certain hill (in feet) is given by h(x, y) = 10(2xy-3x-4y- 18x + 28y + 12), where y is the distance (in miles) north, x the distance east of South Hadley. How steep is the slope (in feet per mile) at a point 1 mile north and one mile east of South Hadley? In what direction is the slope steepest, at that point?
