Multiple Choice

Compute the gradient of the function at the given point.
-f(x, y) = ln(-5x + 3y) , (-9, -4)

A) ${\nabla} f = - \frac { 3 } { 11 } i - \frac { 4 } { 33 } j$
B) ${\nabla} f = - \frac { 5 } { 33 } \mathbf { i } + \frac { 1 } { 11 } j$
C) ${\nabla} f = - \mathrm { i } + \frac { 1 } { 33 } \mathrm { j }$
D) ${\nabla} f = - \frac { 4 } { 33 } \mathrm { i } - \frac { 3 } { 11 } \mathrm { j }$
