Since the options have not been given, I am giving an assumed answer.
A rate is defined as the ratio in which two different kinds of numbers or units are compared. A unit rate allows comparison of the to its units of measurement. Unit rates are expressed as a single quantity or as a quantity of 1. Examples - 5 miles per hour, 2 dollars per pound, 4 feet per second, etc.
So, the best way to calculate the unit rate for a proportional relationship from a graph will be to first check the graph of the relationship. The next step will be to find the y-value of that particular point which corresponds to the point where x = 1. That particular point value is calculated as the unit rate.

Answer:
Step-by-step explanation: Look at the graph of the relationship. Count the number of units up and the number of units to the right one must move to arrive at the next point on the graph. Write these two numbers as a fraction.
