What is the difference of the y-values of two points on a line?

The difference in the y-values of two points on a line is equal to the vertical distance between those points. This difference is also known as the "rise" or the "change in y."

To calculate the difference in the y-values of two points (y₁, x₁) and (y₂, x₂) on a line, you simply subtract the y-coordinate of one point from the y-coordinate of the other:

Difference in y-values = y₂ - y₁

This calculation gives you the vertical distance between the two points on the line.
