Question 4

The graph shows the time it took a worker to package 16 bottles of shampoo. The next day two workers packaged twice the number of bottles of shampoo in the same amount of time. If this new relationship is graphed on the same coordinate grid, which statement is true?

Accepted Answer

The new graph would be steeper than the original graph.

Answer

The new graph would have a y-intercept at 8.

Answer

The new graph would have a y-intercept at 80.

Answer

The new graph would be less steep than the original graph.
