Answer:

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 fr each of the pairs above, are equal to 1/2

Explanation:

Let m1 be first slope


m1 \: = (y2 - y1)/(x2 - x1)= (0 - ( - 2))/(4 - ( - 2))= (0 + 2)/(4 + 2) \\ = (2)/(4) = (1)/(2)

Let m2 be second slope

m2 = (y2 - y1)/ (x2 - x1)

= (2-(-1)) / (4-(-2)

= (2+1) / (4+2)

= 3/6 =1/2

Thus, the slopes are different parallel lines because m1 =m2

Beatrice's conclusion is wrong

All of these points are not on the same line, because are different parallel lines
