Linear
Equation: a mathematical expression that has an equal sign and linear expressions
Variable: a number that you don't know,
often represented by "x" or "y" but any letter will do!
Linear
Expression: a mathematical statement that performs functions of
addition, subtraction, multiplication, and division
Note: Variable(s) in linear expressions
Cannot have exponents (or powers)
For example, x squared or x 2
Cannot multiply or divide each other
For example: "x" times "y" or xy; "x" divided by "y" or x/y
Cannot be found under a root sign or square root sign (sqrt)
For example: � x or the "square root of x"; sqrt (x)

These are examples of linear expressions:
x + 4
2x + 4
2x + 4y
These are not linear expressions:

x2 (no exponents on variables)
2xy + 4 (can't multiply two variables)
2x / 4y (can't divide two variables)
� x (no square root sign on variables)
