The rate of change (ROC) is the speed at which a variable changes over a specific period of time.
First one,
A = (5, 110)
B = (11, 242)
[tex]\begin{gathered} m=\frac{242-110}{11-5} \\ m=\frac{132}{6} \\ m=22 \end{gathered}[/tex]Second one
B = (11, 242)
C = (60, 1320)
[tex]\begin{gathered} m=\frac{1320-242}{60-11} \\ m=\frac{1078}{49} \\ m=22 \end{gathered}[/tex]The two rates of changes are equal and 22
