Answer

They are the same line because the rate of G, H and I are the same.

Work Step by Step

1. (1,-2) (-1,-5) (5,4) $m=\ \frac{b_{1}-b_{2}}{b_{1}-b_{2}}$ 2. $\frac{-2-\left(-5\right)}{1-\left(-1\right)}=\frac{3}{2}$ This is the rate of line A, B. 3. $\frac{-2-4}{-1-5}=\frac{-9}{-6}$ This is the rate of line B and C. The rate of the lines is the same $\frac{-9}{-6}=\frac{3}{2}$
