The graph shows the amount of money Joe earns each hour he works. Determine whether the graph shows a proportional relationship. Explain your reasoning.

• No; the graph is NOT straight and passes through the origin. So, Joe's earnings are NOT proportional to the number of hours he works.

• Yes; the graph is a straight line that passes through the origin. So, Joe's earnings are proportional to the number of hours he works.

• No; the graph is straight and doesn't pass through the origin. So, Joe's earnings are NOT proportional to the number of hours he works.

• Yes; the graph is NOT a straight line that passes through the origin. So, Joe's earnings are proportional to the number of hours he works.
