Pick two points. This graph includes a point that is the y intercept. So let's use that.\r
\n" ); document.write( "\n" ); document.write( " $\"y+=+mx+%2B+b\"$ where m is the slope and b is the y intecept
\n" ); document.write( "Use points (0,1) and (2,2)
\n" ); document.write( "The y intercept is 1 (as given by the point (0,1)). So b = 1
\n" ); document.write( "Now let's find the slope
\n" ); document.write( "m = (y2 - y1)/(x2-x1)
\n" ); document.write( "m = (2 -1)/(2-0) = 1/2\r
\n" ); document.write( "\n" ); document.write( "The equation for the line is $\"y+=+%281%2F2%29x+%2B+1\"$
\n" ); document.write( "and the slope is 1/2 \n" ); document.write( "

\n" );
