Solution Sets to Inequalities with Two Variables 2014-2015 Algebra

TOPIC: Inequalities with Two Variables AIM I can visually represent the solution set to an inequality with two variables. TOPIC: Inequalities with Two Variables

Do Now Hint: Substitute the values for x and y into the inequality. Remember: ( x, y )

Inequalities with Two Variables Have solutions that make a true statement. Solutions can be represented as ordered pairs (points) and are determined based on their location on the graph All of the solutions together are called the solution set

Why would it make sense to call the graph of the line y = 4x – 10 the boundary line?

Practice Graphing Inequalities Write your name and the date on your handout. Look up when you are finished. What do we need to do if we want to graph the equation: x + y = 20

Understanding Inequalities < > In words Boundary Line Shaded Area

Wrap-Up Look over the work you did on your worksheet and make any necessary corrections When you are finished, write 2-3 sentences comparing and contrasting the four graphs you created. DO NOT do the Exit Ticket yet.
