Line Graphs:

Scatterplots:
-Show the relationship between two sets of data. These are used to make predictions
-They can have a positive correlation. This mean that the trend moves up like the one below:
-They can also have a negative correlation. This means that the trend moves down.
-Or there can be no correlation. With no correlation a trend line cannot be put in. A trend line is a line put in to help show the correlation.
I loved that you showed the different types of trend lines. I tried to find some pictures that showed these but I had no luck. These pictures really would help someone who doesn't understand the differences in the trend lines.
