You can put this solution on YOUR website!
First, pick x=0.
\n" ); document.write( " $\"y=-2x\"$
\n" ); document.write( " $\"y%280%29=-2%280%29=0\"$
\n" ); document.write( "You now know the line goes through (0,0), the origin.
\n" ); document.write( "Pick one more point x=1.
\n" ); document.write( " $\"y=-2x\"$
\n" ); document.write( " $\"y%281%29=-2%281%29=-2\"$
\n" ); document.write( "Another point is (1,-2).
\n" ); document.write( "Two points is all you need to define a line.
\n" ); document.write( "(0,0) and (1,-2)\r
\n" ); document.write( "
