No, the slope of a horizontal line is 0. The slope of a vertical line is undefined.
The slope of a vertical line is undefined. Horizontal slope is 0.
A vertical line has an undefined slope. For the line to be parallel to a vertical line, the slopes would have to be the same. Therefore, the line parallel to a vertical line also has an undefined slope.
No. The slope of a horizontal line is zero. The slope of a vertical line is undefined.
The slope of any vertical Line is undefined because anything divided by zero is undefined.
The slope of a line is undefined if the line is vertical.
