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

What word describes the slope of the line passing through points (5 12) and (5 -13)?
It would be a undefined slope.There are four types of slope:Postive slope (when lines go uphill from left to right)Negative slope (when lines go downhill from left to right)Zero slope (when lines are horizontal)Undefined slope (when lines are vertical)
How do you write an equation if the slope is undefined?
Undefined slopes belong to lines that are vertical. These lines do not cross the y-axis, but do cross the x-axis. Therefore, the equation for these lines are always: x = # (where # is the value at which the line is crossing the x-axis).
How can you tell if a slope is zero or undefined?
A slope is 0 if it is a straight horizontal line. A slope is undefined if it is a straight vertical line.
What kind of lines are always the same distant apart?
Parallel lines-lines in the same plane with the same slope.
A horizontal line has a rise which is?
The slope is 0. If it were vertical, the slope would be undefined. APEX ZERO
Do vertical lines always have an undefined slope?
Yes.
Do horizontal lines have an undefined slope?
No. The slope of a horizontal line is zero. The slope of a vertical line is undefined.
What type of slope does vertical lines have?
a slope of zero. horizontal is undefined
Does everyline have a slope and y intercept?
No, vertical lines have an undefined slope.

It would be a undefined slope.There are four types of slope:Postive slope (when lines go uphill from left to right)Negative slope (when lines go downhill from left to right)Zero slope (when lines are horizontal)Undefined slope (when lines are vertical)
When is the product of the slope of two perpendicular lines not equal to -1?
When the lines are horizontal and vertical. (slope of zero) (undefined slope)
How do you write an equation if the slope is undefined?
Undefined slopes belong to lines that are vertical. These lines do not cross the y-axis, but do cross the x-axis. Therefore, the equation for these lines are always: x = # (where # is the value at which the line is crossing the x-axis).
A line parallel to another line with an undefined slope must also have an undefined slope?
Sounds reasonable. If the lines are parallel, then their slopes are equal.
Do vertical lines always have an slope?
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.
Can the graph of a linear functions have undefined slope?
Yes. For example, the lines x=7, x=-1, and x=145 all have an undefined slope; they are all vertical.
Do undefined slopes have a slope?
An undefined slope is just a line straight down. The slope is undefined.
What is the difference between undefined slope and no slope?
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
