If the line runs parallel to the x axis (horizontally), its slope is 0. If runs parallel to the y axis (vertically), then its slope is undefined.
This is because slope equals rise (y) divided by run (x).
For example, if the line is raised 0 units on the y scale and runs 3 units over from the origin on the x scale, you calculate slope by dividing 0 (rise) by 3 (run), which equals 0. On the other hand, if we were to flip the units, the case would be different. If you go up 3 units on the y scale, and over 0 units on the x scale, you would divide 3 (rise) by 0 (run), which is undefined because it is impossible to divide by zero.
No. The slope of a horizontal line is zero. The slope of a vertical line is undefined.
Undefined slope is a vertical line along the horizontal point of origin., the slope would have a denominator of zero, which is undefined.
Undefined.
The slope is undefined.
Sounds reasonable. If the lines are parallel, then their slopes are equal.
A vertical line has an undefined slope.
No, the slope of a horizontal line is 0. The slope of a vertical line is undefined.
An undefined slope is just a line straight down. The slope is undefined.
No. The slope of a horizontal line is zero. The slope of a vertical line is undefined.
An undefined slope is vertical.
A slope is 0 if it is a straight horizontal line. A slope is undefined if it is a straight vertical line.
The equation of a line with an undefined slope is x = a.
zero is horizontal, undefined is vertical
The slope of a line is undefined if the line is vertical.
No, the slope is undefined
Undefined slope is when a line is exactly on the y-axis, for reasons unknown, the slope of a line on the y-axis cannot be determined, so therefore it it "undefined." A line with no slope is a line with a slope of zero. In order for a line to have a slope of zero, it must be directly on the x-axis, meaning it is horizontal. Horizontal lines are straight and have no slope
The slope of a vertical line is undefined. Horizontal slope is 0.
