As in the pervious graph that I posted, this equation is in SLOPE-INTERCEPT FORM, y=mx+b. In this case \"y=%281%2F2%29x+-1+\", the y-intercept is -1, and the slope m=\"1%2F2\"=\"%28RISE%29%2F%28RUN%29+\", which means that the RISE =1, and the RUN =2. Start graphing the y-intercept by going DOWN 1 unit on the y-axis. Put a point there. Now, with your pencil on this point, go UP 1 unit, then go to the RIGHT 2 units, and put another point. Connect the dots. It should look like this:\r
\n" ); document.write( "\n" ); document.write( "\"graph%28300%2C300%2C+-10%2C+10%2C+-10%2C+10%2C+%281%2F2%29x-1+%29+\"\r
\n" ); document.write( "
