    Refer to the Math Notes box in Lesson 4.1.1.

  2. Hernisha’s slope triangle has a slope of . What do you know about her line?

    How does her slope relate to the slope of the line above?

A graph of slope triangle A, slope triangle B, and slope triangle C on the same axis. The three slope triangles all graphed on the same slope line. Slope triangle A has points (0, comma 2), (2, comma 2), and (2, comma 3). Slope triangle B has points (2, comma 3), (8, comma 3), and (8, comma 6). Slope triangle C has points (4, comma 4), (12, comma 4), and (12, comma 8).
