Answer:

y = -¾x + 3

Step-by-step explanation:

Given the equation in standard form, 3x + 4y - 12 = 0, we must isolate the y in order to make it the subject of the equation.

The first step is to add 12 to both sides of the equation:

3x + 4y - 12 + 12 = 0 + 12

3x + 4y = 12

Next, subtract 3x from both sides:

3x - 3x + 4y = - 3x + 12

4y = -3x + 12

Lastly, divide both sides by 4 to isolate y:

[tex]\frac{4y}{4} = \frac{-3x + 12}{4}[/tex]

y = -¾x + 3
