The steepness of a line on a graph is called the?

Answer 1

The "steepness" of a line is called the slope. The slope represents the the amount of change in the y-direction of the line per every change in the x-direction. This is represented mathematically by

slope = Δy/Δx

Δy is also called the "rise" and Δx is also called the "run".

The steepness can also be called the gradient, which is represented by an angle. The gradient can be calculated from the slope by using the formula gradient = tan(slope).
