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.
