They are shown in order of increasing x coordinate. Check to see that the slopes between neighboring-listed points are all equal. .....
.... They are equal.


That means, change in y divided by change in x is the same value between any pair of points listed. Staying with purely algebraic thinking, what you do next depends on which form of equation you are comfortable to use.

Choose ANY point from the list.
PICKING: (4,9);
