teresa makes house calls. for each, she is paid a base amount and makes additional money for each hour she works. the graph below shows her pay (in dollars) versus the number of hours worked. use the graph to answer the questions. (a) how much does her pay increase for each hour worked? (b) what is the slope of the line?

teresa makes house calls. for each, she is paid a base amount and makes additional money for each hour she works. the graph below shows her pay (in dollars) versus the number of hours worked. use the graph to answer the questions. (a) how much does her pay increase for each hour worked? (b) what is the slope of the line?

Answer

Explanation:

Step1: Identify two points on the line

Let's take the points (0, 20) and (1, 40).

Step2: Calculate the change in y - values and x - values

The change in y ($\Delta y$) is $40 - 20=20$, and the change in x ($\Delta x$) is $1 - 0 = 1$.

Step3: Find the rate of change and slope

The rate of change of pay per hour and the slope of the line are given by $\frac{\Delta y}{\Delta x}$. So, $\frac{\Delta y}{\Delta x}=\frac{20}{1}=20$.

Answer:

(a) $20 (b) 20
