What makes an expression linear?

• it has at least one variable to the second power

• it has a variable that isn't multiplied or divided by itself or any other variable

• it has been really good in school and keeps all the math rules in line

• it has a variable

Simplify by combining like terms:
5a + 2b - 3a + 4

• 8a + 2b + 4
• 2a + 2b + 4
• 8ab
• 4ab + 4
