To complete the table, we need to substitute each value of x into the equation and solve for y. Here are the steps:
1. For x = -2:
-10(-2) + y = 4
20 + y = 4
y = 4 - 20
y = -16
So when x = -2, y = -16.
2. For x = -1:
-10(-1) + y = 4
10 + y = 4
y = 4 - 10
y = -6
So when x = -1, y = -6.
3. For x = 0:
-10(0) + y = 4
0 + y = 4
y = 4
So when x = 0, y = 4.
4. For x = 1:
-10(1) + y = 4
-10 + y = 4
y = 4 + 10
y = 14
So when x = 1, y = 14.
5. For x = 2:
-10(2) + y = 4
-20 + y = 4
y = 4 + 20
y = 24
So when x = 2, y = 24.
Hope this helps! Let me know if you have any further questions.
To find the value of y for each x, we can use the function equation provided, which is:
-10x + y = 4
To solve for y, we can rearrange the equation as follows:
y = 10x + 4
Now we can substitute each value of x in the table, to find the corresponding value of y:
When x = -2, y = (10 x -2) + 4 = -16
When x = -1, y = (10 x -1) + 4 = -6
When x = 0, y = (10 x 0) + 4 = 4
When x = 1, y = (10 x 1) + 4 = 14
When x = 2, y = (10 x 2) + 4 = 24
Therefore, the completed table is:

Hope this helps!
For x = -2:
-10(-2) + y = 4
20 + y = 4
y = 4 - 20
y = -16
For x = -1:
-10(-1) + y = 4
10 + y = 4
y = 4 - 10
y = -6
For x = 0:
-10(0) + y = 4
0 + y = 4
y = 4
For x = 1:
-10(1) + y = 4
-10 + y = 4
y = 4 + 10
y = 14
For x = 2:
-10(2) + y = 4
-20 + y = 4
y = 4 + 20
y = 24
Completing the table:
x -2 -1 0 1 2
y -16 -6 4 14 24
Given equation: x - 2y = 4
Substituting x = -2:
-2 - 2y = 4
-2y = 4 + 2
-2y = 6
y = -3
Substituting x = -1:
-1 - 2y = 4
-2y = 4 + 1
-2y = 5
y = -2.5
Substituting x = 0:
0 - 2y = 4
-2y = 4
y = -2
Substituting x = 1:
1 - 2y = 4
-2y = 4 - 1
-2y = 3
y = -1.5
Substituting x = 2:
2 - 2y = 4
-2y = 4 - 2
-2y = 2
y = -1
Now, we have the following completed table:
x | y

-2 | -3
-1 | -2.5
0 | -2
1 | -1.5
2 | -1
