Question

the graph shows the weight of a bag of rice, y, as a function of the number of cups of rice used, x. what is the rate of change of the function? rate of change = \frac{change in y - values}{change in x - values}=\frac{15 - 21}{3 - 0}=\square

Explanation:

Step1: Calculate numerator

$15 - 21=-6$

Step2: Calculate denominator

$3 - 0 = 3$

Step3: Find rate of change

$\frac{-6}{3}=-2$

Answer:

$-2$
