First write the equation, where r and t are variables and k is a constant to be determined:
\n" ); document.write( "r=kt\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Plug in the values of r= -4 and t= 2:
\n" ); document.write( "r= kt
\n" ); document.write( "-4 = k* 2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Divide both sides by 2, and get
\n" ); document.write( "-2 = k\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now substitute that value of k=-2 into the original equation:
\n" ); document.write( "r=kt
\n" ); document.write( "\"r=+-2t\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "R^2 at SCC\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
\n" );
