You can put this solution on YOUR website!
One way to do this is make a system of equations. Use a form, mp+b=A.\r
\n" ); document.write( "\n" ); document.write( "Two equations from your data pairs are:
\n" ); document.write( " $\"m%2A11%2Bb=1950\"$ and $\"m%2A%2811-7%29%2Bb=2250\"$ , which is the system:
\n" ); document.write( "--------------------
\n" ); document.write( " $\"highlight%2811m%2Bb=1950%29\"$
\n" ); document.write( " $\"highlight%284m%2Bb=2250%29\"$
\n" ); document.write( "--------------------\r
\n" ); document.write( "\n" ); document.write( "Solve the equations for m and b any way you want; substitution, elimination, graphing. \n" ); document.write( "
