Question

Which slope would best describe a nearly vertical line and why: 999 or -1?

Answer 1

The slope of a line gives the steepness of the line.

It is evaluated as

`\begin{gathered} m=\frac{\text{rise}}{\text{run}} \\ =(y_2-y_1)/(x_2-x_1) \end{gathered}`

The higher the slope value, the steeper the slope.

Thus, a slope of 999 will have a nearly vertical line.
