The Solution:
Given the linear function below:
[tex]\begin{gathered} f(x)=4.6x+26 \\ \text{Where} \\ f(x)=\text{ the number of graduates from college } \\ x=\text{ number of years after 1998} \end{gathered}[/tex]
So, the slope of the linear function above is the coefficient of x in the given linear function. Therefore, the slope of the given function is 4.6
The interpretation of the slope is 4.6% of the people graduate from college every year after the year 1998.
