Question 80514
<pre><font size = 4><b>
How do I graph x = 3?

Draw a set of axes like this:

{{{graph(300,300,-7,7,-7,7)}}}

Find 3 on the x-axis and draw a vertical
line through it like this:

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

That's all there is to it.

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

By the way, if you had been asked to graph 
y = 3 instead, you would find 3 on the 
y-axis and draw a horizontal line through 
it, like this:

{{{graph(300,300,-7,7,-7,7,3)}}}
