$y = (-9x-14)/2$ or $y = -9/2x - 7$

$-9x - 7 = 2y + 7$

To solve for $y$ , we have to make $y$ by itself.

First, subtract $color(blue)7$ from both sides of the equation:
$-9x - 7 quadcolor(blue)(-quad7) = 2y + 7 quadcolor(blue)(-quad7)$

$-9x - 14 = 2y$

Now divide both sides by $color(blue)2$ :
$(-9x - 14)/color(blue)2 = (2y)/color(blue)2$

Therefore,
$y = (-9x-14)/2$

This can also be simplified to:
$y = (-9)/2x - 14/2$

$y = -9/2x - 7$

Hope this helps!
