The correct graph would be the first one
Since you did not provide options for what 80

x could be equivalent to,, it is near to impossible to answer this question fully. I will simplify 80

x for you and then when you can provide the options for me,, I could help you find the answer if you need it.
To simplify this you must reduce the numbers with 4 in order to find your final answer.
20x.
This means that the correct answer to your question is 20x.
Let me know if you have any further questions.

24: 10
12: 5 is equivalent to 24: 10
Divide both sides by 5 and then n + 2 =2 so the answer is n=0
hope this help
You're performing this kind of transformation:

This kind of transformations translate the functions vertically k units up if k is positive, k units down if k is negative.
So, in your case, you translate the function 7 units down.
