Answer:
Option 1
Explanation:
There are a number of strategies you can use with multiple-choice questions. One of them is to try the answers to see what works. When you employ that strategy, it is useful to pick an answer to try that will let you make the correct choice immediately.
Here, you see that the y-value for x=0 is the same in some tables. However, the y-values for x=4 and x=8 are all different.
So, a suitable point to check is x = 4. If you put that into the equation, you have ...
7(4) -4y = 20
You can divide by 4 to make this a bit simpler:
7 -y = 5
If you add y and subtract 5, you get ...
7 -5 = y = 2
This corresponds to the y-value shown in Option 1.
