The slope of a vertical line is undefined. It either slants straight up or straight down-- you can not say which. The formula for slope does not work in this case because the denominator is zero.

Yes.


What lines always have an undefined slope.?

Vertical lines always have an undefined slope. Slope for y = f(x) is given by :slope = dy/dxdx is zero at any point along a vertical line, making the slope undefined along a vertical line.


Do vertical lines have a slpoe of zero?

No. Horizontal lines have zero slope. Vertical lines have infinite slope.

What is the slope of all vertical lines?

The slope of a vertical line is not defined.


Do vertical lines always have a slope of zero?

No, vertical lines do not have a slope of zero; instead, they have an undefined slope. This is because the change in x-coordinates is zero while the change in y-coordinates can be any value, leading to division by zero in the slope formula (slope = change in y/change in x). Consequently, vertical lines are characterized by a constant x-value and extend infinitely in the vertical direction.

Do all lines have a slope?

Although all lines have the relationship that defines slope, one can argue that not all lines do have one. The exception would be vertical lines. Slope is defined as the vertical rate of change divided by the horizontal rate of change. In the case of a vertical line, there is no horizontal rate of change, and calculating slope would cause division by zero. The closest you could come to expressing the slope of a vertical line would be ∞


What slope do horizontal lines always have?

Horizontal lines always have a slope of 0.
