Question 1125265: The problem requires the following:
Find the slope of the vertical line through the point (9,15).
Since the slope formula requires a second ordered pair, I believe that it would be zero, Since the x2 and y2 coordinates are not given. However, I'm not sure if this is right.

Slope is not defined for a vertical line (slope = rise/run = (y2-y1)/(x2-x1) and run=0 for a vertical line). In some contexts, slope might be called infinite for a vertical line.

A horizontal line has zero slope.
