A.) y=3x-2 is the correct answer.
The y in the equation simply refers to the y-values in the table.
The x in the equation refers to the x-values in the table.
Plug in each answer like so:
y=3(-2)-2 --> -6-2. Here you do a thing called KFC.
Keep
Flip
Change
You Keep -6
You Change the minus sign in front of the 2 to make it a plus sign
And then you change the positive 2 that is left into a negative 2.
-6+(-2)=-8
If you plug in each of the x-values, you then get the corresponding y-value making option A.) correct.

Answer:
73
Step-by-step explanation:
First, to get rid of the square root, square both sides of the equation to get:
y-9=64
Then, move 9 to the other side to get
y=73
