Faraaz Hossain 9-21-08 Block-E Big Idea: Observation and description of changes in the world around us are the first steps in finding and learning about patterns. INV 4: Essential Question: How can I use graphs, tables and symbols to solve problems? MR4:pg60
 * 1) The Larson family is traveling from** **Michigan** **to** **Florida** **at an average speed of 60 miles per hour. Write an equation for a rule you can use to calculate the distance they have traveled after any given number of hours.**

My equation is (d=60xtime). My rule is number of miles traveled is equal to sixty multiplied by the number of hours traveled.


 * 2) What are the advantages of having an equation to represent the Larson family situation?**
 * What are the advantages to having a table? A graph?**

The advantage of an equation that represents the Larson family situation is that if you are predicting the next few hours, then you just need to follow the rule and you will find your answer easily. The advantage of a table that represents the Larson family situation is that, at a glance you can see how many miles and hours the Larson family traveled. The advantage of a graph that represents the Larson family situation is that, you can physically see how much the Larson family traveled as time progressed.


 * Think about your answers to these questions, discuss your ideas with other students and your teacher, and then write a summary of your findings in your journal.**

After investigation four I found out, how to write an equation and rule, and to use that to find out information. I can find out information from a table and graph and basically count out of the table or graph. I also learned to find out the relationship between equations, tables, and graphs.
