Can someone help me with this. I have no idea what to do.

Hey there! Welcome to Brainly!
This is a function table. The equation above the table says that y=x-2. This means that each y-value will be 2 less than its corresponding x-value.
Let's look at -4. It's y-output will be 2 less. This means y will be -6. We do this for each number, giving us our answers below.
x y
-4 -6
-8 -10
-6 -8
1 -1
6 4
I hope this helps you! Have a wonderful time here at Brainly!
Use the given equation.
Replace x with each value of x you are given, and solve for y. Then fill out the table with the values of y you find.
y = x - 2
Let x = -4: y = -4 - 2 = -6
The first line gets -6 for y.
Let x = -8: y = -8 - 2 = -10
The second line gets -10 for y.
Let x = -6: y = -6 - 2 = -8
The third line gets -8 for y.
Let x = 1: y = 1 - 2 = -1
The fourth line gets -1 for y.
Let x = 6: y = 6 - 2 = 4
The fifth line gets 4 for y.
The values you fill in are:
-6
-10
-8
-1
4
