You can put this solution on YOUR website!
the distance (d) you bike varies directly with the amount of time (t) you bike.
\n" ); document.write( " suppose you bike 13.2 mi in 1.25 hours.
\n" ); document.write( " what is an equation that relates d and t? what is the graph of this equation?
\n" ); document.write( ":
\n" ); document.write( "Since we are starting from the origin (0,0), we can determine the slope to be $\"13.2%2F1.25\"$ ,
\n" ); document.write( " hence the equation:
\n" ); document.write( "d = $\"13.2%2F1.25\"$ t
\n" ); document.write( "looks like this
\n" ); document.write( " $\"+graph%28+300%2C+200%2C+-4%2C+10%2C+-10%2C+80%2C+%2813.2%2F1.25%29x%2C+13.2%29+\"$
\n" ); document.write( "You can see when t = 1.25 hrs, d = 13.2 mi (green line), \n" ); document.write( "

\n" );
