the graph below represents claires earnings in dollars and cents, y, for working x hours. find the rate of change.
Answer
Explanation:
Step1: Recall rate - of - change formula
The rate of change of a linear relationship (slope) is given by $m=\frac{y_2 - y_1}{x_2 - x_1}$, where $(x_1,y_1)$ and $(x_2,y_2)$ are two points on the line.
Step2: Identify two points
We have the points $(x_1,y_1)=(10,238)$ and $(x_2,y_2)=(20,476)$.
Step3: Substitute values into formula
$m=\frac{476 - 238}{20 - 10}$.
Step4: Calculate
$m=\frac{238}{10}=23.8$.
Answer:
$23.8$
