Final answer:
The equation with a unit rate greater than the one shown in the graph is y = 7x/16.
Step-by-step explanation:
To find the equation with a unit rate greater than the one shown in the graph, we need to compare the ratios of the y-values to the corresponding x-values. Looking at the graph, we can see that the unit rate is given by the slope of the line. The equation with the smallest slope will have the greatest unit rate. Comparing the slopes of the given options, we can determine that y = 7x/16 has the greatest unit rate.
