What is the definition of slope?

Back

Slope is a measure of the steepness of a line, calculated as the ratio of the vertical change (rise) to the horizontal change (run) between two points on the line.

How do you calculate the slope between two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula: m = (y2 - y1) / (x2 - x1).

How do you find the slope from a graph?

Back

To find the slope from a graph, choose two points on the line, count the vertical change (rise) and the horizontal change (run), and use the formula m = rise/run.
