Final answer:
George should look at point (x, 1) in order to read the unit rate.
Step-by-step explanation:
The point George should look at in order to read the unit rate is option c. (x, 1).
In a proportional relationship, the unit rate represents the constant ratio of the dependent variable (y) to the independent variable (x). In this case, the unit rate would be the ratio of y to x when x equals 1.
For example, if the graph represents a relationship between distance and time, and the unit rate is 5, it means that for every 1 unit of time, the distance increases by 5 units.
