Solving Inequalities in Two Variables
aligned to Hsa.ced.a.3; Hsa.rei.d.12
Learning Objective
I can use graphing technology to find the solution to a two-variable inequality. When given inequalities, graphs, and descriptions that represent the constraints in a situation, I can connect the different representations and interpret them in terms of the situation.

“A student wants to save at least $200 for a concert. They currently have $50 and plan to save money from their weekly allowance of $20. Write an inequality to represent the total amount they need to save, and use graphing technology to graph the inequality. Describe the solution region and what it represents. A baker can make a maximum of 100 cookies in a day. If they make 30 chocolate chip cookies, write an inequality to represent the number of sugar cookies they can make. Use graphing technology to graph the inequality and describe the solution region in the context of the baking situation.”
