You can put this solution on YOUR website!
The slope, m, of a line s defined as $\"m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29\"$ . So just substitute your ordered pairs into that equation to get $\"m=%28-3-4%29%2F%282-2%29\"$ , which simplifies to $\"m=-7%2F0\"$ . Because division by 0 is undefined, that means our slope is undefined. Any line with an undefined slope is a vertical line and that is confirmed by examining the x-values of both ordered pairs here. \n" ); document.write( "
