What do the differences between the points ( as shown on the graph ) represent?
a. 7/2 is the unit rate because it compares the change in y-values to the change in x-values of the points on the graph.
b. 2/7 is the unit rate because it compares the change in y-values to the change in x-values of the points on the graph.
c. 7/2 can be used to find the unit rate if one divides 7 by 2 and compares the result to 1
d. 2/7 can be used to find the unit rate if one divides 2 by 7 and compares the result to 1
