Hopefully this will help you.
There is a rule:
One input(x-value) can only have one output(y-value) in order to be a function.
If one input has more than one output, it is not a function.
(This doesn't apply to outputs, one output can have more than one input and still be a function)
The 1st option is not a function because the inputs 9 and 10 have more than one output.
The 2nd option is not a function because the input 3 has more than one output.
The 3rd option is a function because each input only has one output.
The 4th option is not a function because the input 5 has more than one output.
Answer:In expression x-2 coefficient of x is equal to one.
Let a be "a" x's coefficient.
If we put "a" to Your equation, it should be looks like:
ax-2
We know that there is only one x, so expression ax have to be equal x
Now we get
From this equation we know that coefficient x "a" is equal to 1.
