Examine the graph at right with slope triangles $\text{A}$ , $\text{B}$ , and $\text{C}$ .

Find the slope of the line using slope triangle $\text{A}$ , slope triangle $\text{B}$ , and then slope triangle $\text{C}$ .
Hint (a):
Refer to the Math Notes box in Lesson 4.1.1.
Hernisha’s slope triangle has a slope of $\frac { 1 } { 2 }$ . What do you know about her line?
Hint (b):
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).
