An undefined correlation is one in which the data would not plot with points making a vertical line.

The slope is undefined.
They are both in the same vertical plane.
A line is undefined because all points on the line have the same x-coordinate.

The slope is undefined.
The slope for these two points is undefined, or straight up.
No. A horizontal line has a slope of 0. A vertical line has an undefined slope. Let's say you have a vertical line with the points (3,-2) and (3,4). The slope is (y1-y2)/(x1-x2) = (-2-4)/(3-3) = -6/0 = undefined. Notice that x is the same for both points. A line in which all points have the same value for x is a vertical line and as such has an undefined slope.
They are both in the same vertical plane.
undefined
The x-coordinate must be the same for all points on the line.
