If two lines intersect, then their intersection is one point. - TRUE
The statement given above matches with:
1. If the lines intersections of two lines is a point, then they intersect. (because there is only one solution that is true for both the equations which is the point that they intersect at)
Statement 2 and 3 do not make sense here with respect to the given statement.
For 2, there is no point at all if two lines do not intersect and for 3, it is true that if the intersection of two lines is not any point then they do not intersect each other.
