Answer 1

To determine the unit rate using the graph, we can look at the slope of the line. The slope is equal to the change in y divided by the change in x.

In this case, the change in y is 2 - 0 = 2 and the change in x is 0.8 - 0.4 = 0.4.

Therefore, the unit rate is 2/0.4 = 5.

However, none of the given options match this value. So none of the options provided are correct.
