The answer is graph (b).

Work Step by Step

\SigmaWe can deduce the answer by checking the equation. The equation , first of all, is a linear equation so we are expecting a line. We can immediately see that graph (b) is the only linear graph. Furthermore, by comparing the equation with the general form y=mx+b; we see that the line should be sloping downwards and that it intersects the y-axis at +3. Graph (b) satisfies all conditions, hence it is the answer.
