Scatered Data Forms

My form and table and chart is on this link  on this link to get to the form you need to go to the thing on the tool bar that says Form(45).  Then you go to live form.  The two questions i asked were: How many of your family members live in different countries?, and How many states have you lived in?.  There was no correlation between my two questions.  The picture above is my graph and line of fit.  Also the equation is y=4x+6. 




this is my L1 and L2 chart.

Then i went to my graph and made it a scatter plot by going to zoom and then to zoom stat and my scatter plot appeared.

Then i found the line of best fit by going to stat and then calc and finaly down to #4 on the list.  Like above i found the equation and entered it into y='s like it is on the right.












then i graphed it.

My line of best fit on the graph paper did not match the line of best fit on my calculator.

1st Trimester Reflections

I am proud of my last test.
I wish i had done better on the first test.
Over all algebra has not been hard for me.
Solving equations, ratios, and proportions.
My first goal for the next trimester is to study more for tests.  I will use my practice tests to study and i will use my past HW to study.
My second goal is to get all 20's on my HW.  I can cheek my work and have my mom or dad cheek it.
