Answer 1

To complete the input and output table for the given equation \( y = 2x + 3 \), we will calculate the corresponding value of \( y \) for each value of \( x \) provided in the table.

Here are the values we need to calculate:

1. For \( x = 8 \):
\[
y = 2(8) + 3 = 16 + 3 = 19
\]

2. For \( x = 1 \):
\[
y = 2(1) + 3 = 2 + 3 = 5
\]

3. For \( x = 2 \):
\[
y = 2(2) + 3 = 4 + 3 = 7
\]

4. For \( x = -5 \):
\[
y = 2(-5) + 3 = -10 + 3 = -7
\]

Now we can fill in the output \( y \) values corresponding to the \( x \) inputs:

| \( x \) | \( y = 2x + 3 \) |
|---------|------------------|
| 8 | 19 |
| 1 | 5 |
| 2 | 7 |
| -5 | -7 |

So the completed input and output table is:

| \( x \) | \( y \) |
|---------|---------|
| 8 | 19 |
| 1 | 5 |
| 2 | 7 |
| -5 | -7 |
