Rate of change allows you to quantify the relationship between two changing quantities by calculating the ratio of change in one quantity to the change in the other. It can be found using tables of data by taking the difference in the dependent variable and dividing by the difference in the independent variable. Rate of change can also be found using a graph by choosing two points and calculating the ratio of the change between them. Slope is another term for rate of change and can be found using the points on a graph or using the slope-intercept form of a linear equation.
