The line is vertical.

Explanation:

The general expression for the slope of the line containing two points (x_1,y_1)(x1,y1) and (x_2,y_2)(x2,y2) is (y_2-y_1)/(x_2-x_1)y2−y1x2−x1

However in the case the xx coordinate of both points is the same, so the denominator in this expression would be zero and the slope is infinite/undefined.

The line is vertical.
