The line must pass through: (0,0) and (-1/8, 1/13).
\n" ); document.write( ".
\n" ); document.write( "m = slope = (0-(1/13)) / (0-(-1/8))
\n" ); document.write( "m = -8/13
\n" ); document.write( ".
\n" ); document.write( "y = mx +b
\n" ); document.write( ".
\n" ); document.write( "y = -8/13x + b
\n" ); document.write( ".
\n" ); document.write( "Use one of the points you have to intersect to find 'b'
\n" ); document.write( ".
\n" ); document.write( "1/13 = -8/13(-1/8) + b
\n" ); document.write( "1/13 = 8/104 + b
