Find $\frac{dy}{dx}$ by implicit differentiation. Then find the slope of the graph at the given point. (If an answer is undefined, enter UNDEFINED.) $xy = 28$, $(-7, -4)$ $\frac{dy}{dx} = $ At $(-7, -4)$: $y' = $

          Find $\frac{dy}{dx}$ by implicit differentiation. Then find the slope of the graph at the given point. (If an answer is undefined, enter UNDEFINED.)

$xy = 28$, $(-7, -4)$
$\frac{dy}{dx} = $

At $(-7, -4)$: $y' = $

Find (dy)/(dx) by implicit differentiation. Then find the slope of the graph at the given point. (If an answer is undefined, enter UNDEFINED.)

xy = 28, (-7, -4)
(dy)/(dx) =

At (-7, -4): y' =
