Question

This graph shows how much Marie earns babysitting compared with the number of hours she works select the correct statement about the graph

Answer 1

The answer is D 

The graph reflects that she is getting paid 10 dollars an hour

If you plot the points, you will see she makes 5 dollars every half hour

Answer 2

Answer:

Option D is the answer.

Step-by-step explanation:

This graph represents a linear function representing earnings of Marie at y axis and hours of working at x axis. To get the change in Marie's earnings for every 5 hours we will find the slope of the given line.

Slope of the line will define the rate of change in earning of Marie with respect to the time.

End points of the line at time t = 0 and t = 5 hours are (0, 0) and (5, 50).

Therefore slope = $\frac{y-y'}{x-x'}=\frac{50-0}{5-0}=\frac{50}{5}=10$

So for each hour she works her earnings go up by $10.

Option D is the correct option.
