The slope is 0. If it were vertical, the slope would be undefined. APEX ZERO

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)

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.

The slope of such a line is undefined: If you divide delta y / delta x for any two points, you get a division by zero.

The line rotates anti-clockwise, from a horizontal to a vertical position.

zero is horizontal, undefined is vertical

No. The slope of a horizontal line is zero. The slope of a vertical line is undefined.

A line with an undefined slope is a vertical line. A line with a slope of zero is a horizontal line. If you use the formula for slope m = (y2-y1) divided by (x2-x1)... For an undefined slope you will get zero in the denominator, which you cannot have because you cannot divide by zero. For a slope equal to zero, you will get a zero in the numerator. Zero divided by any non-zero denominator, will give you a slope of zero.

Undefined slope is a vertical line along the horizontal point of origin., the slope would have a denominator of zero, which is undefined.

positive slope negative slope undefined slope zero slope

positive slope negative slope zero slope undefined

a slope of zero. horizontal is undefined

The slope of any vertical Line is undefined because anything divided by zero is undefined.

A line with slope of zero is horizontal. A line with no slope is vertical because slope is undefined on a vertical line.

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

a vertical line has an undefined slope, while a horizontal slope has a slope of zero.

Because slope is defined as change in y over change in x, for a vertical line your change in x is zero. Dividing by zero gives an undefined answer.
