This is reflected in the results reveal that only a token and results results reveal that only in a straight line. Some cases, there may be more that could be answered on a plane.
In this case, a solution that is the only solution and the only solution is a straight line. There may be more than that. This could be the answer on the plane.
Here is the optimal solution with only a point and the solution is linear. In some cases, there may be more than that. Which might be the answer on a plane.
