You can put this solution on YOUR website!
The slope, m, is defined as $\"m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29\"$ . It doesn't matter which ordered pair is $\"x%5B1%5D\"$ , $\"y%5B1%5D\"$ and $\"x%5B2%5D\"$ , $\"y%5B2%5D\"$ because you'll get the same answer. Using substitution we get $\"m=%286-6%29%2F%28-8%2B4%29\"$ . Because the numerator is 0, the slope is 0 and by definition, that's a horizontal line. \n" ); document.write( "
