Question

y = 70 x + 8 Which table gives three values of x and their corresponding values of y for the given equation?

Accepted Answer

Choice A is correct. Each of the given choices gives three values of x : 0 , 2 , and 4 . Substituting 0 for x in the given equation yields y = 70 0 + 8 , or y = 8 . Therefore, when x = 0 , the corresponding value of y for the given equation is 8 . Substituting 2 for x in the given equation yields y = 70 2 + 8 , or y = 148 . Therefore, when x = 2 , the corresponding value of y for the given equation is 148 . Substituting 4 for x in the given equation yields y = 70 4 + 8 , or y = 288 . Therefore, when x = 4 , the corresponding value of y for the given equation is 288 . Thus, if the three values of x are 0 , 2 , and 4 , then their corresponding values of y are 8 , 148 , and 288 , respectively, for the given equation. Choice B is incorrect. This table gives three values of x and their corresponding values of y for the equation y = 4 x + 70 . Choice C is incorrect and may result from conceptual or calculation errors. Choice D is incorrect and may result from conceptual or calculation errors.
