which sets of points are collinear?
two lines intersect at point d. one line has points f, w, d, and r in that order. the other line has points t, e, q, and d in that order.

  Any subset of exactly 2 points from {d, e, f, q, r, t, w} will be collinear.

  Any subset of 3 or more of points {d, f, r, w} will be collinear.

  Any subset of 3 or more of points (d, e, q, t} will be collinear.

Step-by-step explanation:

Points on the same line are collinear. Any two points are collinear, so any pair of the named points will be collinear. Any 3 or more that are on the same line will also be collinear.
