What is the plot of the point with coordinates (-4,3)?

First draw this set of axes, or get some graph paper:



The first coordinate of (-4,3) is -4.  That is the 
x-coordinate. Find -4 on the horizontal axis, and
draw a vertical line through -4, like this:

 

The second coordinate of (-4,3) is 3.  That is the 
y-coordinate. Find 3 on the vertical axis, and
draw a horizontal line through 3, like this:



Draw a dot where those two line cross:



Erase those two lines:




That "o" is the point (-4,3) plotted.

Notice it is directly above the -4 on the
x-axis (the horizontal axis) and it is 
on the same level with 3 on the y-axis
(the vertical axis).  When you have plotted
a few points you will be able to plot them
without having to draw in those two lines
and them erase them.
