Lesson 2-1 Ordered Pairs Obj: The student will be able to write solutions of equations in two variables as ordered pairs HWK: p 52-53 17-30 all, 16, 31, 33 Vocab: 1) algebraic expression 2) equation 3) variable 4) ordered pair

Determine whether each ordered pair is a solution of: y = 3x + 2 Ex 1) (2, 5) Ex 2) (3, 11)

Use the given values to make a table of solutions. Ex 3) y = 8x Ex 4) n = 4m – 3 for x = 1, 2, 3, 4 for m = -4, -3, -2, -1

Ex 5) In most states, the price of each item is not the total cost Ex 5) In most states, the price of each item is not the total cost. Sales tax must be added. If sales tax if 6%, the equation for total cost is c = 1.06p where p is the price before tax. a) How much will Dominic’s $160 set of jerseys cost after sales tax?

b) How much will Alyssa’s $140 set of jerseys cost after sales tax?

Journal entry (put date on paper) Ex 6) Explain why an equation with two variables has an infinite number of solutions.
