A graph is just a way to show every possible
\n" ); document.write( "way that 2 unknown quantities can be related
\n" ); document.write( "Every point on a graph is an (x,y) point
\n" ); document.write( "the x was how you got to that point going
\n" ); document.write( "horizontally. The y is how you got there
\n" ); document.write( "going vertically.
\n" ); document.write( "To build understanding:
\n" ); document.write( "\"y+=+7\" is an equation, it just doesn't involve x
\n" ); document.write( "It should say to you \"I don't care what x is -all
\n" ); document.write( "I care about is that \"y+=+7\"
\n" ); document.write( "Now I'll plot it:
\n" ); document.write( "\"+graph%28+500%2C+500%2C+-2%2C+5%2C+-2%2C+10%2C+7%29+\"
\n" ); document.write( "Looking at the graph, every point on the horizontal line
\n" ); document.write( "says \"I'm at (x,7), and I don't care what x is, because
\n" ); document.write( "x can be anything you want. If you want x to be 3.7025,
\n" ); document.write( "then I will be the point (3.7025,7), and that will be
\n" ); document.write( "on the line \"y+=+7\"
\n" ); document.write( "Now suppose I draw the line \"y+=+0\". That's the
\n" ); document.write( "horizontal line that says \"I don't care what x is as
\n" ); document.write( "long as y is always zero.
\n" ); document.write( "Any point on this line looks like (x,0), and it's
\n" ); document.write( "actually the x-axis
\n" ); document.write( "If I choose (4.7319,0), that is on the x-axis
\n" ); document.write( "Does this help any? Always go back to what
\n" ); document.write( "you're sure of and build your understanding
\n" ); document.write( "up to where it should be -there's no other way
\n" ); document.write( "
\n" );
