Answer:

C. $y = \frac{1}{3}x$

Step-by-step explanation:

All linear equations reflect that the line graph is the straight line.

The linear equation reflecting a straight line has the formula as following: $y = a*x+b$

According to the table, the line graph cross four points: A (-3; -1); B(0;0); C(3;1); D(6;2), which means that the x, y of each point would fit the equation.

So that, we replace the x, y of each point in the equation and have:

1) -1 = a*-3 +b

2) 0 = b

3) 1 = a*3 + b

4) 2 = a*6 + b

From these 4 equations, it can be calculated that: a = 1/3; b = 0

So that the linear equation corresponds to the line graph is: $y = \frac{1}{3}x$
