Practice Slope in Math

Use these practice problems to test your method after reviewing the concept explanation and worked examples.

Quick Recap

A measure of the steepness and direction of a line, calculated as the ratio of vertical change (rise) to horizontal change (run) between any two points on the line. Slope is written as m=y2−y1x2−x1 and indicates how much y changes for each unit increase in x.

How much the line goes up for every step to the right. Steeper = bigger slope.
