The line is vertical.

Explanation:

The general expression for the slope of the line containing two points #(x_1,y_1)# and #(x_2,y_2)# is #(y_2-y_1)/(x_2-x_1)#

However in the case the #x# 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.
