Answer:

line c

Step-by-step explanation:

The graph representing a direct variation equation always passes through the origin. This could be graphs (a) or (c)

given y = $\frac{1}{2}$ x

with slope = $\frac{1}{2}$

Since graph (a) slopes down from left to right it's slope is negative

Hence it is not graph (a) as the slope given in the equation is positive.

Hence the required graph is (c)
