Question

Which of the following lines has an undefined slope?

Answer 1

The slope of a line can be positive, negative, zero, or undefined. A horizontal line has slope zero since it does not rise vertically (i.e. y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x1 − x2 = 0). because division by zero is an undefined operation.

Answer 2

A vertical line has no slope following lines has an undefined slope?

Step-by-step explanation:

• Since it is not divisible by zero, the slope value is of course undefined. This relationship is always true.
• A vertical line has no slope, and "slope not defined" or "line has no slope" means that the line is vertical.Undefined term.
• In geometry, points, lines and planes are considered ambiguous terms because they are described only by way of examples and explanations. Name  points, lines, and planes. A point that is collinear is a point being on the same line.
• All points on a vertical line have the same x-coordinate, so the slope of the vertical line is undefined. Consequently, in the formula used to calculate the slope, the denominator is zero, so the slope is undefined.
