3y = 9 - 12x
Divide by 3
y = 3 - 12/3x
(-12/3 simplifies to -4)
y = 3 - 4x
-4 would be your slope! :)

Answer:

slope = -4

Step-by-step explanation:

3y = 9 - 12x

Rearrange the right-hand side:

3y = - 12x + 9

Next, Divide both sides by 3 to isolate y:

[tex]\frac{3y}{3} = \frac{-12x + 9}{3}[/tex]

y = -4x +3 this is the slope-intercept form where the slope, m = -4, and the y-intercept, b = 3.

Therefore, the slope = -4.
