Enter the location of two coordinate points along a line into the calculator to determine the rate of change of that line.
Rate of Change Formula
Rate of Change = (y₂ – y₁) / (x₂ – x₁)
y₂ = y coordinate of point 2
y₁ = y coordinate of point 1
x₂ = x coordinate of point 2
x₁ = x coordinate of point 1
The rate of change of a line is often referred to as the slope, or rise over run. It’s a measure of how quickly a line is changing in the y direction with every step in the x direction. This can also be done use a similar formula, but substituting x and y in the formula. This results in the rate of change of x with respect to y, or run over rise.
