How to describe points given a matrix and its determinant?

the question

Hi, I'm confused where to even start with this problem. Any help would be appreciated. What do the points have to do with the equation at all? I know if we plug in [a1, a2] for [x1, x2] for example, the matrix would have two rows with the same values, so the determinant would be zero. But how can I relate that to all the points? How are the points related to each other? Are they all equal to each other?

Thanks
