That's an interesting caveat - \"...if it exists...\"
\n" ); document.write( "All lines will have a slope, either positive, negative, zero, or undefined!
\n" ); document.write( "Let's see what your slope is.
\n" ); document.write( " $\"m+=+%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29\"$
\n" ); document.write( "Where:
\n" ); document.write( " $\"x%5B1%5D\"$ and $\"y%5B1%5D\"$ are taken from the first point (2, 5), and...
\n" ); document.write( " $\"x%5B2%5D\"$ and $\"y%5B2%5D\"$ are taken from the second point (3, -9)
\n" ); document.write( "Making the appropriate substitutions, we get:
\n" ); document.write( " $\"m+=+%28-9-5%29%2F%283-2%29\"$ Simplify.
\n" ); document.write( " $\"m+=+-14%2F1\"$
\n" ); document.write( " $\"m+=+-14\"$
\n" ); document.write( "Because the slope is negative, the line through the two given points leans to the left.
\n" ); document.write( "Here's a graph of the line:
\n" ); document.write( " $\"graph%28400%2C400%2C-5%2C5%2C-10%2C10%2C-14x%2B33%29\"$ \n" ); document.write( "

\n" );
