The graph of that line is shown below. The line is x=2 and the slope is undefined because for any two points you choose, x=2 resulting in x1-x2 = 0 in the slope calculation m = (y1-y2)/(x1-x2).

I can't graph vertical lines here, but if it is perpendicular to the x-axis, it is a vertical line, and its value is the x-value of the point, which is 2.
x=2 is a vertical line through x=2 and any y-value. It is perpendicular to the horizontal x-axis.
