\n" ); document.write( "\n" ); document.write( "Start with the first equation:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 1: Select a value for . It can be anything you like, but the arithmetic is generally simpler if you choose a small integer.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 2: Substitute the selected value for in your equation and then solve for .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 3: Create an ordered pair using the selected value from Step 1 and the calculated value from Step 2.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 4: Plot the point represented by the ordered pair derived in Step 3.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 5: Repeat steps 1 through 4 using a different value of .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 6: Now that you have two points plotted, draw a straight line all the way across your grid passing through the two plotted points.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 7: Repeat steps 1 through 6 using the second equation.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 8: The solution set is the ordered pair that represents the point where the two graphed lines intersect.\r
