Question 81221
write the equation of the line passing through each of the given points with the indicated slope. Give your results in slope-intercept form, where possible.
(2,-3)and (2,4)
<pre><b><font size = 5>
Plot those two points 

{{{ drawing(300,300,-5,5,-5,5,

locate(1.9,-2.6,o), locate(1.9,4.3,o),locate(2.5,-2.6,"(2,-3)"), 

locate(2.5,4.3,"(2,4)"),  

graph(300,300,-5,5,-5,5))}}}

and draw a line through them:

{{{ drawing(300,300,-5,5,-5,5,

locate(1.9,-2.6,o), locate(1.9,4.3,o), locate(2.5,-2.6,"(2,-3)"), 

locate(2.5,4.3,"(2,4)"), 
graph(300,300,-5,5,-5,5,99999(x-2)))}}}


It's a vertical line!
A vertical line has no slope so it has
no slope-intercept form. Its equation is
just simply

        x = 2

because every point on that vertical line 
has 2 as its x-coordinate,
