Question 941689
<pre>
Plot the point (-1,1)

The first coordinate -1 is the x-coordinate

Find -1 on the x-axis and draw a vertical line through it,
like this in green

{{{drawing(400,400,-4,4,-4,4, graph(400,400,-4,4,-4,4),

green(line(-1,-10,-1,10)) )}}} 

The second coordinate 1 is the y-coordinate

Find 1 on the y-axis and draw a horizontal line through it,
like this in red:

{{{drawing(400,400,-4,4,-4,4, graph(400,400,-4,4,-4,4),
red(line(-10,1,10,1)),
green(line(-1,-10,-1,10)) )}}} 

Notice where the green and red lines cross.  Draw a dot there.

{{{drawing(400,400,-4,4,-4,4, graph(400,400,-4,4,-4,4),
red(line(-10,1,10,1)),
circle(-1,1,0.15),circle(-1,1,0.13),circle(-1,1,0.11),circle(-1,1,0.09),circle(-1,1,0.07),circle(-1,1,0.05),circle(-1,1,0.03),circle(-1,1,0.01),
green(line(-1,-10,-1,10)) )}}} 

Erase the green and red lines and label the point (-1,1):

{{{drawing(400,400,-4,4,-4,4, graph(400,400,-4,4,-4,4),
locate(-2.05,1.3,"(-1,1)"),
circle(-1,1,0.15),circle(-1,1,0.13),circle(-1,1,0.11),circle(-1,1,0.09),circle(-1,1,0.07),circle(-1,1,0.05),circle(-1,1,0.03),circle(-1,1,0.01) )}}} 

Notice that is directly above -1 on the x axis and right beside 1 on the
y-axis.
