Question

The graph shows the amount of money Miguel earns after working x hours.



What is the ratio of the change in y-values to the change in x-values for this function?

1:13
2:5
5:2
13:1

Answer 1

The answer is

13:1

So the answer is D

Answer 2

Thank you for asking this question. Here is your answer:

Solution 1

The change of x would be:  Δ x = 5 - 2 = 3

The change of y would be:  Δ y = 65 - 26 = 39

Δ y : Δ x = 39 : 3 = 13 : 1

Solution 2

Change in y value : (65 - 26) = 39

change in x values : (5 - 2) = 3

Ratio is : 39:3 ( or 39/3) reduces to 13:1 (or 13/1)
