Station 1 DIRECTIONS: Solve each system by GRAPHING ! After you find the point of intersection, check that it is the correct solution by testing it in BOTH equations! 1) 7 6 2 3 = - = + y x y x 2) 10 4 2 10 2 = + = + y x y x 3) 3 3 1 1 3 1 - = + - = x y x y 4) 4 5 3 = + = y x y

Together their ages add up to 22. How old is Mary? 2) Tammy and Dana bought pens and pencils. Tammy bought 4 pens and 5 pencils, and her total bill was $6.71. Dana bought 5 pens and 3 pencils, which cost her $7.12. How much does each pen and each pencil cost? (Let X equal the price of a pen and Y equal the price of a pencil.) Station 6 DIRECTIONS: Write each linear inequality in slope-intercept form. Then graph the inequality. 1) 6 3 5 -y x 2) 8 6 4--x y 3) 6 3-y 4) 8 3 +- x y 5) 2 4 1--x y...
