Answer:
Triangles A and E could lie on a graphed lin with a slope of 6
Triangles B and F could lie ona graphed line with a slope of 1/4
Triangles C and D could lie on a graphed line with a slope of 2/5
Explanation:
The slope is rise over run.
Triangle A goes up 54 and to the right 9 so the slope is 54/9=6
Triangle B goes up 15 and to the right 60 so the slope is 15/60=1/4
Triangle C goes up 18 and to the right 45 so the slope is 18/45=2/5
Triangle D goes up 16 and to the right 40 so the slope is 16/40=2/5
Triangle E goes up 72 and to the right 12 so the slope is 72/12=6
Triangle F goes up 13 and to the right 52, so the slope is 13/52=1/4
From there we can find which slopes are the same.
