WebDec 9, 2024 · 1. Understand the slope formula. Slope is defined as “rise over run,” with rise indicating vertical distance between two points, and run indicating the horizontal distance between two points. [2] 2. Pick two points on the line and label their coordinates. These can be any points the line runs through. WebTo find the equation of line in slope-intercept form when two points (x₁, y₁) and (x₂, y₂) on a line are given, Find the slope using m = (y₂ - y₁) / (x₂ - x₁). Substitute it in the equation y = mx + b. Substitute any one of the given points to be (x, y) in the above equation and solve for b.

WebJan 12, 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.
