How do you find the rate of change between ordered pairs?

To find the rate of change between ordered pairs, you calculate the difference in the y-values (output) and divide it by the difference in the x-values (input). This is expressed as the formula: Rate of Change = (y₂ - y₁) / (x₂ - x₁), where (x₁, y₁) and (x₂, y₂) are the two ordered pairs. The result represents how much y changes for a unit change in x.
