Answers to Knowledge Section of COW#7, Tuesday

1. f(x) = 2x – 5, m= 2 b=-5
2. y=2x +5, m= 2 b=5
3. f(x) =-2x-5, m= -2 b=-5
4. f(x) =-2x+5, m= -2 b=5
5. y = 4x –1, m= 4 b=-1
6. y = 3x + 2, m= 3 b=2
7. f(x) = -3x + 2, m= -3 b=2
8. y = 3/5 x + 2, m= 3/5 b=2
9. f(x) = -3/5 x + 5, m= -3/5 b=5
10. y= 3/2 x -6, m= 3/2 b=-6

You should be working on IXL. V2-V6, V11, and V7. Remember, you need to get to 80%.

COW #6- FUNCTIONS Continued

COW #6

From the last two weeks, we all know how to identify functions from a graph by using the vertical line test. Now, we will work with equations and tables and learn how to determine the difference between a relation and a function.

COW #5 and REVIEW WEEK

This week we will be reviewing the concepts that we have learned so far this year: coordinate graphing, slope, rate, and functions. We will have a unit assessment on Friday to determine how well we understand these concepts. This week's COW asks you to complete some problems and to create step by step directions/procedures for how to solve them. Take this work seriously as it will help you to focus for the assessment Friday.

Cow #5- Review

This week we will also be working in the computer lab three times. We will be working on fluency with math facts and reviewing the concepts from the last 5 weeks of school using Math Facts in a Flash and http://www.ixl.com . I encourage you to practice on both of these sites at home throughout the week as well. MAKE SURE TO SIGN IN, so that I can see how hard you are working. You will get your passwords tomorrow.

Finally, we will be summing up the Oil Spill Project this week as you create your final presentations for your role. I am looking forward to your creative productions!

Please let me know if you have any questions about what we have studied so far. I want this to be a week where we work especially hard to clear up any misconceptions, misunderstandings, or insecurities.
