y = 576 2 x + 2 The graph of the given equation in the xy -plane has a y

Question

y = 576 2 x + 2 The graph of the given equation in the xy -plane has a y -intercept of r , s . Which of the following equivalent equations displays the value of s as a constant, a coefficient, or the base?

Accepted Answer

Choice A is correct. The y -intercept of a graph in the xy -plane is the point where x = 0 . Substituting 0 for x in the given equation, y = 576 2 x + 2 , yields y = 576 2 0 + 2 , which is equivalent to y = 576 2 , or y = 331,776 . Therefore, the graph of the given equation in the xy -plane has a y -intercept of 0 , 331,776 . It follows that r = 0 and s = 331,776 . Thus, the equivalent equation y = 331,776 x + 1 displays the value of s as the base. 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.
