My Math Casts

My screen casts are HERE, HERE, HERE, and HERE


How you make a math cast: First you go to screenr.com and set up an acount.  Then you download painter which is a program that allows you towrite on a document.  The yo go back to screenr and press record.  After that you go back to Painter and when you are ready you press the red button on the screen.  After that you solve a problem and you are finished.
I liked the Math Casts and they were very helpful to me!!

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.
