In the x-y plane, point (x, y) is a lattice point if both x and y are integers. An ellipse has a center at (0, 0) and minor/major axes lengths of 1, 4, respectively. Some points, such as the center (0, 0), are inside the ellipse, but a point such as (0, 2) is on the ellipse but not in the ellipse. How many lattice points are in the ellipse?
