Question 308032
Just substitute the value into x, and solve for y.

i) x=0

y=1/3(0) -2
y=0-2
y=-2


(0,-2) is a point.


ii) x=3

y=(1/3)*3 - 2
y=1-2
y=-1


(3,-1) is another point.

iii) y=(1/3)*(-3) - 2
y=-1-2
y=-3


(-3,-3) is the last point. 


Plot those three points on a graph, and then connect the dots to draw the line. If you want to see a picture of this, let me know.
