You can put this solution on YOUR website!
You only need two coordinates to graph a linear equation because the graph is a straight line.\r

\n" ); document.write( "\n" ); document.write( "y=2x+5
\n" ); document.write( "Let x=0
\n" ); document.write( "y=2(0)+5=5
\n" ); document.write( "So, when x=0, y=5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "y=2x+5
\n" ); document.write( "Let y=0
\n" ); document.write( "0=2x+5
\n" ); document.write( "-5=2x
\n" ); document.write( "-5/2=x
\n" ); document.write( "So, when y=0, x=-5/2=-2.5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You now have your two coordinates (0,5) and (-2.5,0). Plot the two points on a graph, draw a line through them, and you have your graph.\r
