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 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.
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)
What is the slope of a vertical line?
Good question. They have infinite slopes. Incidentally, vertical lines are not functions in the formal sense. One x value is mapped on to an infinite number of y values. A function requires that each x maps on to only one y value.
Give some real examples of vertical lines?
Vertical lines are lines that go straight up and down, with no horizontal component. Some real examples of vertical lines include the edges of a door frame, the corner of a bookshelf, and the sides of a skyscraper. These lines have a slope that is undefined, as they have no horizontal change.
