Solution:
The question asks to select the coordinates for two points that have a vertical distance between them of 2 units.Let's evaluate the provided options:A) (2, 1) - To have a vertical distance of 2 units, we would look for a point that is either 2 units above (i.e., (2, 3)) or 2 units below (i.e., (2, -1)) this point. However, no such points are listed in the options.B) (1, 0) - Following the same logic as above, we need a point that is (1, 2) or (1, -2). No points with x = 1 and y = 2 or -2 are provided.C) (1, 0) - This option is repeated in the list; therefore, it does not provide a pair of points by itself, so it doesn't satisfy the condition.D) (1, 2) - One way to have a vertical distance of 2 units from this point is to have the point (1, 0), which is also listed in the options.E) (2, 1) - This is the same as option A and doesn't provide a pair with a vertical distance of 2 units.Based on this evaluation, the points that have a vertical distance between them of 2 units are (1,2) and (1,0), which is option B matched with option D.
