Back

A coefficient is a numerical factor that multiplies a variable in an algebraic expression.

Front

Identify the variable in the expression: 8x - 9.

Back

The variable is x.

Front

What is a constant in an algebraic expression?

Back

A constant is a fixed value that does not change, such as -7 in the expression x - 7.

Front

What do we call a letter in math that represents an unknown number?

Front

How do you identify the coefficient in an expression like -9 + -5x?

Back

The coefficient is the number that is multiplied by the variable, which is -5 in this case.

Front

What is the difference between a variable and a constant?

Back

A variable can change and represent different values, while a constant remains the same.

Front
