Find the slope (1,2),(-1,-2)

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.

im guessing (23,14). hope this : )

is there more info provided? there is not enough information given in the problem
