Question

Which answer choice best describes f(x) = x - 12?

A. The relationship shows a direct linear variation with a constant variation of-12.
B. The relationship shows a direct linear variation with a constant of variation of 12.
C. The relationship shows a direct linear variation with a constant variation of 1.
D. The relationship does not show a direct linear variation.

Answer 1

D

a direct linear variation equation has the form f(x) = kx

f(x) = x - 12 is not in this form thus does not show a direct linear variation
