You can look it up in an algebra book or calculus book for more details,
but basically, the command above is saying to plot the points (3, t) for
any t between -10 and 10. In other words, plot points with x-coordinate
3 and y-coordinate "t", where t goes between -10 and 10.
That said, William's suggestion of using the line command might be easier.
