A lattice point is a point in a Cartesian coordinate system such that both its - and -coordinates are integers. A lattice point is a point at the intersection of two or more grid lines in a regularly spaced array of points, which is a point lattice. In a plane, point lattices can be constructed having unit cells in the shape of a square, rectangle, hexagon, and other shapes. If not specified, a point lattice is usually a point in a square array. Lattice points are complicated, so don't get stressed if you don't get it right away! Here's an example to help you to understand it better:
Example
A point lattice is constructed by plotting all of the points such that and are positive integers. How many points in the point lattice lie on the line ?
Solution
Notice that . So, and are the only such points, giving us points.
