A lattice point in the $xy$-plane is a point both of whose coordinates are integers (not necessarily positive). How many lattice points lie on the hyperbola $x^2-y^2=17$?

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.

its line 2 i just added the rest or else it wouldn't let me answer
