To convert the equation [tex]\( y = x - 7 \)[/tex] to standard form, follow these steps:
1. Start with the given equation:
[tex]\[ y = x - 7 \][/tex]
2. Rearrange the equation so that all terms involving variables are on one side and the constant is on the other side. This can be done by subtracting [tex]\( y \)[/tex] from both sides:
[tex]\[ x - y = 7 \][/tex]
This is the standard form of the given equation. Therefore, the correct standard form of the equation without spaces and in lower-case is:
```
x-y=7
```
