It's like measuring how quickly a hill goes up or down. We find the slope by seeing how much we go up or down (vertical change) for each step to the right (horizontal change). If a line goes up 2 steps for every 1 step to the right, its slope is 2. video https://cdn.kastatic.org/googleusercontent/s1jE8xrZxjyUjYW3PI9BB1Mxz4E7equCqGbkEukkpuVrWYXLUscHO_DmhTAhux9EjAYmTOCAJx8fqDbDaAbwlEg Intro to slope Slope tells us how steep a line is.

The slope, or steepness, of a line is found by dividing the vertical change (rise) by the horizontal change (run). The formula is slope =(y₂ - y₁)/(x₂ - x₁), where (x₁, y₁) and (x₂, y₂) are the coordinates of two points on the line.
