Which of the following is a set of collinear points?
A. A, H, B
B. E, F, G
C. B, H, F
D. D, L, B
Which set of points are collinear?
A. F, C, E
B. D, L, F
C. A, B, D
D. H, G, C
E. B, F, G
Yes, first is D
Sorry, second is not B since points D, L, F are not on the same line.
Collinear means that all points are on the same line.
For example, in the first picture, A-H-B does not work, because if you find where they are, they don't form a straight line.
However, D-L-B is in a straight line, so choice D is correct.
With this info, can you do number 2?
You are very welcome!
