What number is delta in math?

The difference between two values of a variable is often called its "delta": that is, given two points on the plane, the "delta y" is the difference between their y-values. For example, given the two points ( 2 , 1 ) and ( 5 , − 7 ) , the delta x is 3 and the delta y is -8.
