1. WARM UP: Graph the following inequality:

2. SUMMARY
*Review from last class*

4. Clarification:
-You should practice using the same method at all times to gain confidence:
Solid or dashed?
Graph the line
using x-int and y-int
slope intercept form
Test Point
Shade

5. We can also apply this idea to word problems!

6. What inequality represents the goal?
let x = number of pairs of skis
let y = number of snowboards
100x +120y > 600
Are there any restrictions?
Since half a snow board, or a third of a pair of skis cannot be sold, the 

solution set is discrete.
xεW, yεW

7. inequality xεW, yεW x intercept 10x = 60 x = 6 (6, 0) y intercept
restrictions
10x + 12y = 60
x intercept
10x = 60
x = 6
(6, 0)
y intercept
12y = 60
y = 5
(0, 5)
{(x,y) Ι 100x + 120y > 600, xεW, yεW}

8. Let's try another together!

9. Independent Practice:
-Additional Practice for 5.1
-Word Problem Applications due tomorrow!

10. Your Turn: (to hand in at the end of class)
