Question 80516
<pre><font size = 5><b>
What is the plot of the point with coordinates (-4,3)?

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

{{{graph(300,300,-8,8,-8,8)}}}

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:

{{{graph(300,300,-8,8,-8,8, 999(x+4))}}} 

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:

{{{graph(300,300,-8,8,-8,8, 999(x+4),3)}}}

Draw a dot where those two line cross:

{{{drawing(300,300,-8,8,-8,8,
   locate (-4.15,3.5,o),

graph(300,300,-8,8,-8,8, 999(x+4),3))}}}

Erase those two lines:


{{{drawing(300,300,-8,8,-8,8,
   locate (-4.15,3.5,o),

graph(300,300,-8,8,-8,8))}}}

That "<font size = 2>o</font>" 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.
