finite geometry

[prinsinn]

Let L and M be distinct nonparallel lines in an affine plane of order n. What is the total number on L U M?


I hope someone knows how to solve this problem.

What is the total number on L U M?


what do you mean by that ?
The order of the two lines together is just 2n ( n points on every line and no points in common because of parrallelity?? )
