use the slope and y-intercept to graph the equation $\"y=2%2F3\"$ $\"x%2B1\"$
\n" ); document.write( "

\r\n" );
document.write( "The y-intercept is the point (0,1), since  is the last number in the equation\r\n" );
document.write( ".  Find 1 on the y-axis.  Put a dot there:\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Now look at the slope, which is , because it is the coefficient\r\n" );
document.write( "in the equation  It has a numerator and a \r\n" );
document.write( "denominator (if it were just a whole number you would put a 1 under\r\n" );
document.write( "it so it would have a numerator and a denominator)\r\n" );
document.write( "\r\n" );
document.write( "The slope is positive, so we start at the point 1 on the y-axis, and\r\n" );
document.write( "from there we draw a line UPWARD the number of units of the NUMERATOR 2.\r\n" );
document.write( "That is, we draw this green line UPWARD which is 2 units long:\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "(You don't have to put an arrowhead on it like I did to\r\n" );
document.write( "show that we went UPWARD.) \r\n" );
document.write( "[If the slope had been negative, we would have drawn\r\n" );
document.write( "it DOWNWARD)]\r\n" );
document.write( "\r\n" );
document.write( "Now from that arrowhead, turn RIGHT (always RIGHT, even when the\r\n" );
document.write( "slope is negative) and draw a line to the RIGHT which is the same \r\n" );
document.write( "number of units long as the DENOMINATOR of the slope, which is 3.\r\n" );
document.write( "So we draw this horizontal line from that arrowhead. I'll put\r\n" );
document.write( "another arrowhead on it, but of course you don't have to, but you\r\n" );
document.write( "can if you like :-)\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Next get a ruler and draw a line through the point you\r\n" );
document.write( "started at, the y-intercept (1,0) through that second\r\n" );
document.write( "arrowhead like this:\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
