BUBBLE BABY-  A bubble baby is a line path that shows you were the equation is going.
 

                                    How to make a Bubble Baby
 
                                1.  You have to look at your scatter plot to see which model it is.
                                2. After you figure what model it is  then you use the equation it has, and fiddle with it. (ex.  Linear is y = mx+b)
                                3. When you go into the Y= you have to put the equation on one of the lines.

                               4.  When you put the equation on the line you also have to change the back slash in front of the Y to a bubble baby sign by pressing enter until it comes up ( picture above shows what it should look like).
                               5. When you start to fiddle with the equation you need the Default values. (Ex.  M = 1, and B = 0)   Here is what it should look like with these starting values.

                                6.  What you are going to do is make M tilt up, so you have to fiddle with it.

1. After you are done with fiddling with it you also have to fiddle with B till you get the equation right. Then you are done , and can show it to Mr. Young and Print it out.
