Answer: y=-1/6x+2
Step-by-step explanation: The point goes through (0,2), aka, the b point in y=mx+b (The slope intercept form). Then because it’s proceeding downwards, we know that the slope is negative. So down one, over 6. This make its -1/6.
So, this question is basically asking us "If we had an x instead of a 2, would this be true?" We can try and see what we get:

So, if we want to show this we have to change the numerator or denominator in such a way that we can cancel some common factors. Notice that 
If we replace the factored numerator with the original one, we get:

Since we have an equality, this relation is proved.
