Question

the financial aid office at khan university produced an internal report on the number of students receiving scholarships. students receiving scholarships according to the graph, what was the rate of change between 2015 and 2018? round your answer to the nearest tenth. students per year

Explanation:

Step1: Identify the formula for rate of change

The formula for rate of change is $\frac{y_2 - y_1}{x_2 - x_1}$, where $(x_1,y_1)$ and $(x_2,y_2)$ are two points on the line. Here, $x$ represents the year and $y$ represents the number of students. For 2015 ($x_1 = 2015$), $y_1=60$ and for 2018 ($x_2 = 2018$), $y_2 = 20$.

Step2: Substitute values into the formula

$\frac{y_2 - y_1}{x_2 - x_1}=\frac{20 - 60}{2018 - 2015}=\frac{- 40}{3}\approx - 13.3$

Answer:

$-13.3$
