What is the slope of.... 1. Vertical Line The slope of a vertical line is undefined. This is because slope is defined as rise over run as the rate of change. A vertical lines "rise" is infinite, but it doesn't move along the x axis, so the denominator of the slope would be 0, which is undefined.

2. Horizontal Line A horizantal line doesn't "rise" so a 0 would be placed in the numerator to determine the slope. The denominator would be infinitely many units that the line moves parallel to the x axis. This would result in a 0 slope.
