Question

If the function f(x)=-1/2x-7 were graphed, which of the following would be true? A. The y-values would be negative. B. As the x-values increase, the y-values would increase. C. The x-values would be negative. D. As the x-values increase, the y-values would decrease.

Answer 1

D.

As the x-values increase, the y-values would decrease.

Answer 2

f(x)= -1/2x-7 (better expressed as f(x) = (-1/2)x - 7 ) has a negative slope, so as x increases, y decreases. Answer D is correct.
