You can put this solution on YOUR website!
how can i solve the system by graphing.
\n" ); document.write( "E1: 2x + y = 4
\n" ); document.write( "E2: x + y = 3
\n" ); document.write( ":
\n" ); document.write( "For E1: let x=0 and solve for y.
\n" ); document.write( "2(0)+y=4
\n" ); document.write( "0+y=4
\n" ); document.write( "y=4 Plot (0,4)
\n" ); document.write( "Now let y=0 and solve for x.
\n" ); document.write( "2x+0=4
\n" ); document.write( "2x=4
\n" ); document.write( "2x/2=4/2
\n" ); document.write( "x=2 Plot (2,0)
\n" ); document.write( "Connect the points and you have a line.
\n" ); document.write( " $\"graph%28300%2C200%2C-10%2C10%2C-10%2C10%2C-2x%2B4%29\"$
\n" ); document.write( "For E2: let x=0 and solve for y.
\n" ); document.write( "0+y=3
\n" ); document.write( "y=3 Plot(0,3)
\n" ); document.write( "Let y=0 and solve for x.
\n" ); document.write( "x+0=3
\n" ); document.write( "x=3 Plot (3,0)
\n" ); document.write( "Connect the points and you have another line:
\n" ); document.write( " $\"graph%28300%2C200%2C-10%2C10%2C-10%2C10%2C-2x%2B4%2C-x%2B3%29\"$
\n" ); document.write( "They connect at (1,2)<--this is the solution of the system.
\n" ); document.write( "Happy Calculating!!! \n" ); document.write( "
