You can put this solution on YOUR website!
Note: I can tell that the system

, can be transformed into the equivalent equation $\"4x%2B2y=-8\"$ by multiplying both sides of the equal sign times 2. If a point is a solution of one equation, it is a solution of the other one. All the points in the line are intersection points and solutions.

\n" ); document.write( "To graph one line you need to plot two points and connect them with a straight line.
\n" ); document.write( "Using grid paper is recommended.
\n" ); document.write( "For $\"2x%2By=-4\"$
\n" ); document.write( "Substituting $\"x=0\"$ gives us $\"y=-4\"$ and we have the point (0,-4).
\n" ); document.write( "Substituting $\"y=0\"$ gives us $\"2x=-4\"$ --> $\"x=-2\"$ and we have the point (-2,0).
\n" ); document.write( "For $\"4x%2B2y=-8\"$ ,
\n" ); document.write( "we could substitute $\"x=0\"$ and $\"y=0\"$ to get
\n" ); document.write( " $\"x=0\"$ --> $\"2y=-8\"$ --> $\"y=-4\"$ for point (0,-4), and
\n" ); document.write( " $\"y=0\"$ --> $\"4x=-8\"$ --> $\"x=-8%2F4\"$ --> $\"x=-2\"$ for point (-2,0)
\n" ); document.write( "

The points are the same for both lines because both lines are the same. \n" ); document.write( "
