Answer:
See the answers below.
Step-by-step explanation:
[tex]Slope\:=\:\frac{Rise}{Run}\:=\:\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{6}{100}=\frac{3}{50}[/tex] (Option C. is right choice.)
The constant rate of change is given by the slope as:
[tex]m=\frac{20-10}{30-15}\\\\m=\frac{10}{15}\\\\m=\frac{2}{3}[/tex]
Option H. is the right choice.
Best Regards!
