[tex]\frac{12}{7}[/tex]
Explanation
Step 1
A rate of change is a rate that describes how one quantity changes in relation to another quantity. If x is the independent variable and y is the dependent variable, then
[tex]\text{rate of change=}\frac{change\text{ in y }}{\text{change in x}}=\frac{y_2-y_1}{x_2-x_1}[/tex]
then select the 2 poitns of the line, Let
P1(5,60)
p2(12,72)
Step 2
replace
[tex]\begin{gathered} \text{rate of change=}\frac{change\text{ in y }}{\text{change in x}}=\frac{y_2-y_1}{x_2-x_1}=\frac{72-60}{12-5}=\frac{12}{7} \\ \text{rate of change=12/7} \end{gathered}[/tex]
I hope this helps you
