which statement is true of the graph on the right? the average salary doubled between year 1 and 2. the…

Explanation:

Step1: Estimate salary in year 1

From the graph, the average - salary in year 1 is approximately $43,000$.

Step2: Estimate salary in year 2

The average - salary in year 2 is approximately $45,000$.

Step3: Estimate salary in year 3

The average - salary in year 3 is approximately $47,000$.

Step4: Check the first statement

The salary in year 1 is about $43,000$ and in year 2 is about $45,000$. Since $45000\neq2\times43000$, the average salary did not double between year 1 and 2.

Step5: Check the second statement

The salary in year 1 is about $43,000$ and in year 3 is about $47,000$. Since $47000\neq3\times43000$, the average salary did not triple between year 1 and 3.

Step6: Check the third statement

The increase from year 1 to year 2 is $45000 - 43000=2000$. The increase from year 2 to year 3 is $47000 - 45000 = 2000$. The average salary increased by the same amount each year.

Answer:

The average salary increased by the same amount each year.
