Scatter Plots on TI-84


Go to youtube.com.  Find a video you like on scatter plots.  Click "share" and then "blogger".  The video will then be embedded in a blog post.  Click "Edit HTML" on upper right corner.  Paste this entire blog into that post and complete it.  When finished, post.

Name three things you learned from this youtube video:
1)how to use the use the scatter plot to get y=mx+b


2)how to put some random numbers and put them to a graph and see what the imformation you are looking for.


3)you can always plat them your self or plot them in the computer so it is easy for you



Now answer the following questions.  Post a link that you used to help you research it.
1) What is a scatter plot?

a bunch of ramdom numbers you place in a piece of paper and you can
find the 0 or y=mx+b

2) What is a line of best fit?
is where the line touches the x axis and where the dots are plotted



3) What is a curve of best fit?
no it is not well it also depends of how you want to use that sertain information


4) Name 2 examples where scatter plots are used in real life:

y=mx+b
inverse variation & direct variation


5) Write an equation of a best fit line for the following scatter plot:



    -At 11 units, what is a good prediction for amount of minutes?




6) Find a scatterplot problem, paste it in here and give the answer.
