Hello!
Given two points (x1, y1) and (x2, y2), the slope of the line that passes through them is very simple to find. Just use this formula:

In this case, however, the slope of this line would be infinite, because the line that passes through the points you mentioned is vertical (notice that the x-coordinate is the same for both points).
If there is a typo in the points you stated, just use the formula I gave you witth the correct values in order to find the slope of the line.

I hope this helps!
