Answer
The given equation represents a linear function as it can be rewritten in the form $y=mx+b$.
Work Step by Step
The given equation is $\frac{x}{4}+\frac{y}{12}=1$.
$\implies y=12(1-\frac{x}{4})$
Or $y=-3x+12$
All linear functions can be represented by the equations of the form $y=mx+b$.
The given equation represents a linear function as it can be rewritten in the form $y=mx+b$.
