b) y = f(x) = -3x+4
Step-by-step explanation:
<u><em>Explanation</em></u>
Given that the equation 9x+3y =12
Let 'x' be an independent variable and 'y' be the dependent variable then the function is of the form
y = f(x)
3 y = 12 - 9x

y = -3x+4
The function represented by y = -3x+4
The answer is the first one:y=2x+35
