Which of the following statements is true about the triangles shown on the graph?

• The slope of the two triangles are the same.

• The triangles are congruent triangles.

• The slope of the larger triangle is larger than the slope of the smaller triangle.

• The slope of the smaller triangle is smaller than the slope of the larger triangle.

Explain whether or not the triangles shown could lie on the same line.

• Yes, because their slopes both simplify to -6.

• Yes, because their slopes both simplify to 1/6.

• No, because -72/12 is not the same as -144/24
