Locate All the Integer Points between Two Integer Points

gridlines

show points

endpoint 1: (1, 1)

endpoint 2: (1000, 100)

number of lattice points between (1, 1) and (1000, 100) is: 10

This Demonstration lets you find the number of integer points on the line segment connecting any two given integer points whose coordinates are in the range from 0 to 1000. (An integer point, sometimes called a lattice point, has both coordinates as integers.)
