Question

How do i write 3y-9x=24 in function notation

Answer 1

To write an expression in function notation, you must solve it for the dependent variable.

Assuming that you want the expression to be written in the form $y = f(x)$ (i.e., assuming that x is the independent variable), we have to solve the expression for y, which means that we want y to remain alone on the left hand side, and move everything else to the right hand side.

So, first of all, we can add 9x to both sides to get

$3y = 9x+24$

Finally, we divide both sides by 3:

$y = 3x + 8$
