Answer: D.  [tex]y = \frac{-3x}{2} - 15[/tex]

Step-by-step explanation:

-3x - 2y = 30

Slope intercept form is y = mx + b

just solve for y

  1. Add -3x to both sides:

-2y = 3x + 30

    2. divide both sides by -2

[tex]\frac{-2y}{-2} = \frac{3x + 30}{-2}[/tex]

    3. simplify

[tex]y = \frac{-3x}{2} - 15[/tex]
