Proportional and linear functions are almost identical in form. The only difference is the addition of the “ b ” constant to the linear function. Indeed, a proportional relationship is just a linear relationship where b = 0, or to put it another way, where the line passes through the origin (0, 0). So a proportional relationship is just a ...

Functions A Function is Special. A function is a type of equation. A function has special rules it must follow: In a function there can ONLY be ONE output(y) for every input (x).
