An upward-sloping, straight diagonal line begins at the point left parenthesis 0 comma 0 right parenthesis and passes through plotted the points left parenthesis 0.4 comma 1 right parenthesis and left parenthesis 0.8 comma 2 right parenthesis. The x-axis ranges from negative 2 to 2 in increments of 1. The y-axis ranges from 0 to 4 in increments of 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.
