5. Using Parallel and Perpendicular Lines

To complete the table, you have to substitute the values of x into the formula and calculate the corresponding y-values.
| x | - 2 | - 1 | 0 | 1 | 2 |
|---|---|---|---|---|---|
| y=x+9 | 7 | 8 | 9 | 10 | 11 |
To complete the table, we should calculate corresponding values of y for the different values of x. To do that, we have to substitute the value of x into the equation y=x+9 and simplify.
If we do this for the rest of the values of x, we can complete the table.
| x | - 2 | - 1 | 0 | 1 | 2 |
|---|---|---|---|---|---|
| Substitution | -2+9 | -1+9 | 0+9 | 1+9 | 2+9 |
| y=x+9 | 7 | 8 | 9 | 10 | 11 |
