Question

The line graph shown below is of the amount of money astudent earns at a part time job, per hour. What is the students wage rate (in terms of dollars per hour)?

Answer 1

From the question let us take any two points.

Let's take (1, 10) and (2, 20)

We have rate as

`\begin{gathered} =(20-10)/(2-1) \\ =(10)/(1) \\ =10 \end{gathered}`

Hence the answer is $10 per hour
