Ambrose has indifference curves represented by the equation x2 = constant - 4x1^1/2, where larger constants correspond to higher indifference curves. If good 1 is drawn on the horizontal axis and good 2 on the vertical axis, what is the slope of Ambrose's indifference curve when his consumption bundle is (9, 19)?
