\n" ); document.write( "\n" ); document.write( "You cannot determine the slope using only the

-intercept, or by using any other single point for that matter. You need two points to uniquely determine a line.\r

\n" ); document.write( "\n" ); document.write( "Consider the equation

where

is any real number. The graph is a line passing through the origin with a slope of

. The

-intercept is the origin, but the slope is

and since

is any real number, there are an infinite number of lines with the the specified

-intercept all with different slopes.\r
