Question

x y 1 11 2 19 3 a The table shows three values of x and their corresponding values of y for the equation y = 4 2 x + 3 . In the table, a is a constant. What is the value of a ?

Accepted Answer

Choice B is correct. It's given that the table shows three values of x and their corresponding values of y for the equation y = 4 2 x + 3 . It's also given that when x = 3 the corresponding value of y is a , and a is a constant. Substituting 3 for x and a for y in the given equation yields a = 4 2 3 + 3 , or a = 35 . Therefore, the value of a is 35 . Choice A 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.
