find the value of r so the line that passes through each pair of points has the given slope.
\n" ); document.write( "(r,3),(5,9),m=2
\n" ); document.write( "**
\n" ); document.write( "For given line:
\n" ); document.write( "slope=2=∆y/∆x=rise/run=change in y/ change in x
\n" ); document.write( "slope=(9-3)/(5-r)=2
\n" ); document.write( "6/(5-r)=2
\n" ); document.write( "10-2r=6
\n" ); document.write( "2r=10-6=4
\n" ); document.write( "r=2\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
