Answer: [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
The average rate of change of a linear function (the slope) is constant.
The rate of change of the linear relationship=[tex]\frac{\text{change in y}}{\text{change in x}}[/tex]
The rate of change from x=1 to x=7
=[tex]\frac{11-2}{7-1}=\frac{9}{6}=\frac{3}{2}[/tex]
Similarly you can check the rate of change for every interval, it would be
[tex]\frac{3}{2}[/tex].
