The correct answers are A. and C.
The rate of from Table A can be calculated by finding the slope, which is

. Therefore, the slope is

, which simplifies to 15.2.
The rate of Relationship B has to be more than 15.2. The slope of a line is the 'm' in the equation 'y=mx+b". In the answer choices, the 'm' values are 16.4, 14.9, 15.4, and 15.2. The only values that are greater than that are 15.4 and 16.4, so your answer is A and C.
