I'm working with the SAS University Edition, and I'm having trouble creating a scatter plot from a dataset with three X variables. It seems like this should be really simple, but I can only seem to add one X value. I have a homework assignment where my instructor asked us to "Plot the observed data and the two fitted regressions on one plot (this is probably easiest done by hand over a scatterplot of the data)." Here is the data set:

Can you provide an example of what such a plot would look like?

I don't think so, because I'm not even sure what it would look like myself... unless my instructor means I should create a separate scatterplot for each X variable?

I think he's asking us to do something like what's being done in this video using a different program... https://www.youtube.com/watch?v=_5kRBBqQhA0

PROC SGSCATTER will create such a scatterplot with 3 x-variables and one-y variable. An example is given here:
