what is slope of a line that passes throught(1,1)(1,2)
\n" ); document.write( "-------------
\n" ); document.write( "slope = change in y/change in x
\n" ); document.write( "---
\n" ); document.write( "= (2-1)/(1-1)
\n" ); document.write( "= 1/0
\n" ); document.write( "which is \"undefined\".
\n" ); document.write( "---
\n" ); document.write( "If you plot the two points and draw a line
\n" ); document.write( "thru the 2 points you will see that you
\n" ); document.write( "get a vertical line that contains all of
\n" ); document.write( "the points where x = 1.
\n" ); document.write( "That is the equationof the \"line\" and
\n" ); document.write( "it has an \"undefined\" slope.
