Plot the point with coordinates (–4, 3).

-------------------

Here's a little better explanation for a beginner
at plotting points.

Draw a set of axes, like this

{{{graph(300,300, -7,7,-7,7)}}}
  
Find the first number, -4, on the x-axis, the 
horizontal axis. Using a ruler draw a light 
pencil vertical line through -4 like the 
green one below:

{{{graph(300,300, -7,7,-7,7, 0,9999(x+4))}}} 

Now find the second number, 3, on the y-axis, the 
vertical axis. Using a ruler draw a light 
pencil horizontal line through 3 like the 
blue one below:

{{{graph(300,300, -7,7,-7,7, 0,9999(x+4),3)}}}

Now mark a dot where the green and blue lines
cross, like the little "o" marked below:

{{{drawing(300,300, -7,7,-7,7, 

   graph(300,300, -7,7,-7,7, 0,9999(x+4),3),

   locate(-4.24,3.45,o) ) }}}  

Now erase the green and blue lines:

{{{drawing(300,300, -7,7,-7,7, 

   graph(300,300, -7,7,-7,7),

   locate(-4.24,3.45,o) ) }}}  

That "o" sitting there marks the point (-4,3).

Notice that the "o" hovers directly above the -4
on the x-axis and is on the exact same level as the
3 on the y-axis.  After plotting a few points, you 
will soon see that it is really not necessary to 
draw the green and blue lines as I did, since you 
can just imagine them being there. Or, to be 
accurate you can use a small card and place it so 
that a vertical side of the card is on the first 
number and a horizontal side of the card is on the 
second number, like this, where the rectangle below 
is the card, and mark the point at the corner of the 
card:

{{{drawing(300,300, -7,7,-7,7, 
 
   rectangle(-4,-1, 4,3),   
 
   graph(300,300, -7,7,-7,7),

   locate(-4.15,3.45,o) ) }}}
 

It is common to write the coordinates of the point
close to the point, like this:

{{{drawing(300,300, -7,7,-7,7, 

   graph(300,300, -7,7,-7,7),

   locate(-4.24,3.45,o),   

   locate(-6.8,3.45,"(-4,3)")
    ) }}}
