Adding and Subtracting Linear Expressions

Front

What is a linear expression?

Back

A linear expression is an algebraic expression in which each term is either a constant or the product of a constant and a variable raised to the first power (exponent equal to 1).

Front

What is a non-linear expression?

Back

A non-linear expression is an algebraic expression that contains variables with exponents greater than 1.

Identify the linear expression: 7y + 5 - y, 4x + x^2 + x, -9 + y^2 + x.

Back

7y + 5 - y is a linear expression.

Front

What happens when you subtract a linear expression?

Back

When you subtract a linear expression, you change the subtraction sign to an addition sign and change the signs of the terms in the second expression.
