Question

x = 49 y = x + 9 The graphs of the given equations intersect at the point x , y in the xy -plane. What is the value of y ?

Accepted Answer

Choice A is correct. It's given that the graphs of the given equations intersect at the point x , y in the xy -plane. It follows that x , y represents a solution to the system consisting of the given equations. The first equation given is x = 49 . Substituting 49 for x in the second equation given, y = x + 9 , yields y = 49 + 9 , which is equivalent to y = 7 + 9 , or y = 16 . It follows that the graphs of the given equations intersect at the point 49 , 16 . Therefore, the value of y is 16 . Choice B is incorrect and may result from conceptual or calculation errors. Choice C is incorrect and may result from conceptual or calculation errors. Choice D is incorrect and may result from conceptual or calculation errors.
