There are really two ways to solve this problem. One of them is the slope formula. You can familiarise yourself with this formula

`\sf{(y2-y1)/(x2-x1)}`

SUBSTITUTE the values

`\sf{(-13-8)/(17-17)}`

`\sf{\frac{-21}{\bf{0}}` (notice the zero was in bold-face)

Dividing by zero is an operation we cannot do.

So the slope of this particular line is not defined.

The other way is looking at the first co-ordinates of the points given

Notice that they are exactly the same. Whenever that happens, the slope of that line is not defined.

Hope that made sense !!
