Which of the following equations, when graphed in the $x-y$ coordinate plane, is perpendicular to $y = -\frac{3}{4} x -2$ and passes through $(3,-4)$?

$y = \cfrac{4}{3} x - 8$

$y = \cfrac{4}{3} x$

$y = -\cfrac{3}{4 }x + \cfrac{25}{4}$

$y =-\cfrac{3}{4} x + \cfrac{7}{4}$

$y = \cfrac{3}{4} x + \cfrac{7}{4}$
