What are linear equations and functions?

Linear Equations produce straight lines when graphed.

Linear Function is an algebraic equation in which each term is either a constant or the product of a constant and (the first power of) a single variable.

•A linear function is defined as a function that has either one or two variables without exponents.

•A linear function is a polynomial function whose graph gives a straight line. The linear function formula is of the form. y=f(x)=mx+c.

A linear equation is an algebraic equation in which each term is either a constant or the product of a constant and a variable. This variable is always single power form. A simple example of a linear equation with only one variable, x, may be written in the form: ax + b = 0, where a and b are constants and a ≠ 0.

4x and 6y

im not sure though
