LINEAR BUBBLE BABY
This web page is designed to show you how to
correctly and quickly use the bubble baby in Y= on your ti calculator.
I did not know how to make a bubble baby until this year, I thought it
was going to be hard but once I learned how it was easy and fun. I'm going
to take you through step by step and teach you how to make a linear bubble
baby.
-
A bubble baby is an equation that best fits a
graph the equation changes depending on the shape of your graph.
-
A linear equation is just a strait line.
-
The linear is Ax*B which is the simplest A controls
the height and the B controls the tilt.
-
In order to make an equation into your graph you
must put your equation into Y=.
-
The best way to get your equation close is to
first look at your data and find the lowest number and put that in for
A.
-
You B are the tilt so see how far your numbers
jump from and put that in for the B.
-
This should get you close to your graph but you
might have to do a little adjustment on your B to get it right on.
-
The best way that I like doing the BB is the automatic
way the first step to that is go to the home screen, and on the 82 hit
stat calc and then pick your BB you want. In this case it is a strait line
so we want linear #5. Next hit enter and it takes you to your home screen
with some numbers. Finally go to Y= hit vars #5 and go over to EQ and then
go down to #7 RegEQ. Now it takes you back to your Y= and makes the equation
for you now all you have to do is hit graph.

Here is an example problem for you to help you
understand it a little better.
