Find the critical point of the given function and then determine whether it is a local maximum, local minimum, or saddle point. (Order your answers from smallest to largest x, then from smallest to largest y.)

f(x, y) = (x − y)(xy − 9)

The vertex of this parabola is at (-2,-3). when the x-value is -1, the y-value is -5. what is the coefficient of the squared expression in the parabola's equation?

Iwill give brainliest. suppose tommy walks from his home at (0, 0) to the mall at (0, 5), and then walks to a movie theater at (6, 5). after leaving the theater tommy walks to the store at (6, 0) before returning home. if each grid square represents one block, how many blocks does he walk?
