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 ∞

Do vertical lines have a slpoe of zero?

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 is the slope of non vertical lines?


Why cant equations of vertical lines be written in slope-intercept form but equations of horizontal lines can?

For vertical lines, when you try to figure out the slope, you get zero in the denominator - in other words, a division by zero.
