We have to choose the pair of points from that given in the attached file which will result in a line with a rate of change i.e. slope of 2:1 i.e. 2.
A. The points are (-4,-11) and (-2,-7).
Then the slope of the joining line is
B. The points are (5,6) and (-5,12).
Then the slope of the joining line is
C. The points are (0,-3) and (-4,-11).
Then the slope of the joining line is
D. The points are (0,-3) and (5,7).
Then the slope of the joining line is
Therefore, options A, C, D are true. (Answer)
