find the slope of the line that passes through the two points. here are the points: (1/2,3/5) and (1/4,-4/5)
\n" ); document.write( "--------------
\n" ); document.write( "First find the slope, m
\n" ); document.write( "m = diffy/diffx = (-7/5)/(-1/4) = -28/-5
\n" ); document.write( "m = 28/5
\n" ); document.write( "-------
\n" ); document.write( "Then use y=mx + b and either point to find b, the y-intercept
\n" ); document.write( "3/5 = (28/5)*(1/2) + b = 14/5 + b
\n" ); document.write( "b = -11/5
\n" ); document.write( "------
\n" ); document.write( "--> y = (28/5)x - 11/5
\n" ); document.write( "Oh, you only asked for the slope. nm
\n" ); document.write( "
\n" );
