Standards:

• 8.EE.C.7a Give examples of linear equations in one variable with one solution, infinitely many solutions, or no solutions. Show which of these possibilities is the case by successively transforming the given equation into simpler forms, until an equivalent equation of the form x = a, a = a, or a = b results (where a and b are different numbers).
• 8.EE.C.7b Solve linear equations with rational number coefficients, including equations whose solutions require expanding the expressions using the distributive property and collecting like terms.

Unit Vocabulary

Coefficient: The number that is multiplied by the variable in an algebraic expression.

Distributive Property: For all real numbers a, b, and c, a(b + c) = ab + ac, and a(b - c) = ab - ac.

Equivalent Equations: Expressions that have the same value for all values of the variables.

*Infinitely Many Solutions: When the variable in an equation can hold any value and the equation will be true.

Intersection: Lines that have one and only one point in common.

*Inverse Operation: Operations that undo each other: addition and subtraction, or multiplication and division.

Linear Equations: An equation whose solutions form a straight line on a coordinate plane.

*No Solutions: There is no value which can make the equation true.

*One Solution: A value or values that make an equation true.

*Substitution: To replace a variable with a number or another expression in an algebraic expression.

*System of Equations: A set of two or more equations that contain two or more variables.

Variables: symbols used to represent a quantities that can change.
