You can put this solution on YOUR website!
5 x + 2 y = 8
\n" ); document.write( "y= -5/ 2x +4
\n" ); document.write( "Assume values of x and plug in the equation to get values of y.
\n" ); document.write( "Plot the points
\n" ); document.write( "x 0 4 2
\n" ); document.write( "y= 4 -6 -1
\n" ); document.write( "(x,y) (0,4),(4,-6),( 2-1) \r
\n" ); document.write( "\n" ); document.write( "--------
\n" ); document.write( "1 x + -1 y = 3
\n" ); document.write( "y= 1 x + -3
\n" ); document.write( "
\n" ); document.write( "Assume values of x and plug in the equation to get values of y.
\n" ); document.write( "Plot the points
\n" ); document.write( "x 0 4 2
\n" ); document.write( "y= -3 1 -1
\n" ); document.write( "(x,y) (0,-3),(4,1),( 2,-1)\r
\n" ); document.write( "\n" ); document.write( "
