Preferably, all of them.
If you have fantastic data, you should be able to draw a straight line through all of the points.
However, this is not true in most cases.
When you have a scatterplot where not all of the points line up, you have to try your best to draw a line that goes through the middle of the group of points, like this:
You can find the exact line that "best fits" your points by using a graphing calculator (it should be called "linear fit").

A rough guide is to have approx half the points above and half of them below the line. You can find the mean of the
#x# values and the mean of the#y# values and ensure the line passes through this point but it does not have to for most questions.
