Answer explanation

Choice D is correct. It’s given that the graph shows the linear relationship between x and y . The given graph passes through the points 0,-5, 1,-3, and 2,-1. It follows that when x = 0 , the corresponding value of y is -5 , when x = 1 , the corresponding value of y is -3 , and when x = 2 , the corresponding value of y is -1 . Of the given choices, only the table in choice D gives these three values of x and their corresponding values of y for the relationship shown in the graph.

Choice A is incorrect. This table represents a relationship between x and y such that the graph passes through the points 0,0, 1,-7, and 2,-9.

Choice B is incorrect. This table represents a relationship between x and y such that the graph passes through the points 0,0, 1,-3, and 2,-1.

Choice C is incorrect. This table represents a linear relationship between x and y such that the graph passes through the points 0,-5, 1,-7, and 2,-9.
