2 points on this line are, for example, (-2,4) and (-2,18.33).
The line is vertical (parallel to y-axis).
The slope is undefined.

The equation represents a line which crosses the -axis at the point (,) . Every ordered pair with as its first coordinate is a solution .
so, points are:
(,)
(,)
A vertical line has slope because all points on the line have the same x-coordinate. As a result the formula used for slope has a denominator of, which makes the slope undefined.
