Web12 jan. 2024 · The slope of a line is the ratio between the vertical and the horizontal change, Δy/Δx. It quantifies the steepness, as well as the direction of the line. If you have the formula of the line, you can determine the slope with the use of the derivative. In the case of a line, this derivative is simply equal to the coefficient in front of the x. Web10 sep. 2024 · As mentioned before, the slope indicates the inclination of the line with respect to the x-axis. This slope is calculated by dividing the vertical distance by the horizontal distance between two points on a line.
