1. Linear Equations and Inequalities

2. Properties of Equality
Match each example with the Property of Equality that it shows.
Let a, b, and c be real numbers.
If a = b, then a + c = b + c.
If a = b, then a – c = b – c.
If a = b, then ac = bc.
If a = b, then a ÷ c = b ÷ c.
Multiplication Property of Equality
Addition Property of Equality
Division Property of Equality
Subtraction Property of Equality

3. Properties of Inequality
Match each example with the Property of Inequality that it shows.
Let a, b, and c be real numbers.
If a < b, then a + c < b + c.
Multiplication Property of Inequality
Addition Property of Inequality
Division Property of Inequality
Subtraction Property of Inequality
If a > b, then a – c > b – c.
If a < b, c > 0, then a ÷ c < b ÷ c,
and if a < b, c < 0, then a ÷ c > b ÷ c.
If a < b, c > 0, then a × c < b × c,
and if a < b, c < 0, then a × c > b × c.
