Solve the systems of linear equations by graphing\r
\n" ); document.write( "\n" ); document.write( "y=2x+9
\n" ); document.write( "y=6-x
\n" ); document.write( "=============
\n" ); document.write( "y = 2x + 9
\n" ); document.write( "They're straight lines.
\n" ); document.write( "To graph them you need 2 points.
\n" ); document.write( "Pick 2 values for x and find y
\n" ); document.write( "eg, x = 0; y = 9 --> the point (0,9)
\n" ); document.write( "x = -2, y = 5 --> the point (-2,5)
\n" ); document.write( "Plot the 2 points, draw a line thru them.
\n" ); document.write( "=====================
\n" ); document.write( "Do y = 6-x the same way.
\n" ); document.write( "---
\n" ); document.write( "The intersection of the 2 lines is the solution of the system.
\n" ); document.write( "
\n" ); document.write( "
\n" );
