Okay, here we have this:

Considering the provided graph, we are going to calculate the requested equation, so we obtain the following:

So let's remember that to obtain the equation of a straight line of the form y=mx+b, we need to know the slope and the y-intercept, so we have:

Slope=(y2-y1)/(x2-x1)

Slope=(3-2)/(3-0)

Slope=1/3

And we can see that the y-intercept is y=2, so we finally get the following equation of the line:

y=mx+b

y=1/3x+2

Finally we get that the correct answer is the third option.
