How do i answer this equation? -3x+y=12. i'm supposed to find the function for it bt i don't know how. can you guys me out

Step-by-step explanation:

We have been given an equation in standard form . We are asked to write our given equation as a function.

We know that the function represents a relationship between input and output, where each input gives exactly single output.  

To write our given equation as a function we need to convert our given equation into slope-intercept form of equation because in slope-intercept form, there is exactly one y output for each input of x.

, where,

m = Slope,

b = The y-intercept.

To convert our given equation into slope-intercept form, we need to get y on left side of our equation.

Now our equation is in form of a function, where each value of x gives exactly one y value.

the five is the numerator
