The slope of a line is defined as m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29. So just substitute your points into that equation to get m=19%2F0. Because division by 0 is undefined, that means the slope is undefined. You can also tell by just examining the two ordered pairs -- because they both have the same x-value, that means you have a vertical line and all vertical lines have undefined slopes.
