Answer 1

A scatterplot is simply a plot of all of the data points you have on a cartesian plane.  In other words, you take all your points, put them down on a graph, and that's about it.

Of course, there's a lot you can do with this, and depending on what your teacher has asked for, you may have to do a little bit more explanation.  For example, you can describe the linearity of data with a scatterplot by assessing the correlation coefficient and a regression plot, etc.

If you want a more in depth analysis, Wikipedia can do you no wrong: http://en.wikipedia.org/wiki/Scatter_plo...  Also, you could always consult your math book, which will be more useful for determining what you need to know for the level of math you're at.
