### Linear Relations Jan.19.2011

Hey guys so Today in class we learned about Linear Relations ...

1) The first thing we did in class was copy some words down so if you didn't get these words here are all that we wrote during notes...

coefficient
variable
constant
linear relation
linear equation
interpolate
extrapolate

2) So the next thing we did was do some questions that Mr. Bake gave us and the questions were about the flowers (red roses, pink roses, and carnations) and we had to spend all of the money to figure out how much flowers we would get at the end and how many possibilities we could do differently...

All flowers and No change all money has to be used
1. pink roses \$2.00 carnations \$1.00 and you only gotta use 10 dollars

So there were 6 possibilities for this answer and here they are...

Pink roses Carnations Money
5-0 10
4-2 10
3-4 10
2-6 10
1-8 10

2. red roses \$5.00 carnations \$1.00 and this time you only gotta us 27 dollars

So there were also 6 possibilities for the answer and they are...

Red Roses Carnations Money
5- 2 27
4- 7 27
3-12 27
2-17 27
1-22 27
0-27 27

3.red roses \$5.00 pink roses \$2.00 and you only gotta use 37 dollars

So there were only 4 possibilities

Red roses Pink roses Money
7-1 37
5-6 37
3-11 37
1-16 37

So you can see that when you look at these 3 questions there is also a pattern in them because in question 1 you can see that the graph is ascending and descending orders and they go up by 2's and down by 1's....

For question 2 the pattern is going up by 5's and going down by 1's

For question 3 the pattern for this question is that is it going up by 5's and down by 2's

.... So yeah here is what we did in class today and just a REMINDER that you guys gotta hand in your stash-it on Friday to make any changes ( i think) and the computer assignment with :

Words
Definition
Picture
Example
Non-example

AND!! for homework you guys gotta finish the graph Mr bake gave us!!

Well since no one or I mean sometimes people who do the scribe maybe will be chose tomorrow I guess but yeah thanks for reading my scribe post!!
P.S please correct me if I made any mistakes but anyway see ya!!
