October 19th

Today we learned some new terms:

Relations  - two things are connected (like relatives ;) .  We can show this relation in ordered pairs, tables or graphs.

Interpolate

Extrapolate

We looked at ways that tables, ordered pairs and graphs can be used to show different relationships

• # tickets to the play Usher are $5 each.  We made a table of values showing # tickets sold and total cost.  
• # minutes cell phone use to cost for the phone can be used to determine if this is cheaper for you than buying a monthly plan

We looked at different graphs to determine if it made sense to join the line and make it continuous.

We started looking at  equations and making a table of values, then graphing the ordered pairs.

Homework:

Worksheet:  1a, 2d, 3ac, 4,5,6
Workbook: pg 12, 13, top 14, top 15.

We also did a notebook check.  Looking good everyone!
