1. Graph the inequality > or < indicate ___boundary lines. > or < indicate ___ boundary lines. To find the area to be shaded test a point. Unless the boundary line goes through the origin a good test point is dashed solid Systems: Remember the left brace indicates the word “and” means that the solution must satisfy sentences. together both

2. Algebra 1 Mr. Gallo

3. Graph the solutions to the system Step 1: Graph the boundary line and solution set for x > 5 Step 2: Graph the boundary line and solution set for y < -2 Step 3: Shade the area that is common to both graphs. The solution to the system is the set of points that are to both. solutions Solution Set

4. Graph the solutions to the system

5. Suppose two positive numbers x and y have a sum that is less than 20 and a difference that is greater than 10. Show all possible values for x and y. Write the system of inequalities: Graph the solution to the system:

6. f p Miss Moffat is planning refreshments for a party. She decides to have at least 10 but no more that 15 pounds of salad- some potato and some fruit salad. She wants to have at least four times as much fruit salad as potato salad. Write a system of inequalities to describe this situation. Let p and f be the number of pounds of potato and fruit salad, respectively: Graph the number and pounds of each kind of salad that she can have:

7. Graph the solutions to the system No solutions
