- Intro to Slope
Learn how to calculate the slope of a line between two points using the formula m = (y2 – y1)/ (x2 – x1) or m = rise/run. Also, find out the slope of a line equation, the angle between two lines, and the conditions for parallel, perpendicular and collinear lines.
In math, the formula for slope is used to determine the steepness of a line that passes through two or more points. One of the most basic characteristics of slopes is that they can be positive (↗ increasing from left to right), negative (↘ decreasing from left to right), zero (↔ a horizontal line), or undefined (↕ a vertical line).
Learn how to calculate the slope of a line by dividing the change in height by the change in horizontal distance. See examples, interactive diagrams, and definitions of positive, negative, zero, and undefined slope.
Learn how to calculate the slope of a line using the formula m = (y2 - y1)/(x2 - x1) or m = tan θ. Find out the types of slope and see examples of slope of horizontal and vertical lines.
Learn how to use the slope formula to find the direction of a line given two points. See how to identify vertical and horizontal lines, and check your answers with online tools and worksheets.
Learn how to find the slope of a line from its equation, graph or two points. The slope is the rate of change of y with respect to x and can be positive, negative or zero.
