Question

Beatrice calculated the slope between two pairs of points.

She found that the slope between (-3, -2) and (1, 0) is 12.

She also found that the slope between (-2, -1) and (4, 2) is 12.


Beatrice concluded that all of these points are on the same line.


Use the drop-down menus to complete the statements about Beatrice's conclusion.


Beatrice is (correct/incorrect). All of these points (are/ are not) on the same line because the slope between (-2,-1) and (1,0) (is/ is not) equal to 1/2.

Answer 1

Beatrice is incorrect. All of these points are not on the same line because the slope between (-2, -1) and (1, 0), which are coordinates from each of the pairs above, is not equivalent equal to 1/2
