Answer:
![y = x](https://img.qammunity.org/2021/formulas/mathematics/middle-school/dno6h0bj75e191jjww04drv86s9zsn5cu4.png)
Explanation:
The given equation is
![y = x + 5](https://img.qammunity.org/2021/formulas/mathematics/middle-school/hcdcobdh75pauao2j8y1f12bis4gf4qj95.png)
The slope of this line
![m = 1](https://img.qammunity.org/2021/formulas/mathematics/middle-school/ehhvdvg4ec4zbko3u8mamdzjjsadz1z4m5.png)
Since all parallel lines have the same slope, the slope of our line is also m=1.
We now use the point-slope formula
![y-y_1=m(x-x_1)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/ks7lzc9jj3emt3ptrdvrvr0uzhz4c0qyo5.png)
Since the line passes through (-1,-1)
We gave
![x_1=-1,y_1=-1](https://img.qammunity.org/2021/formulas/mathematics/middle-school/9504h7rdmywmg0z9ppc6rvj2d046d9hgly.png)
We substitute the slope and point to get
![y - - 1 = 1(x - - 1)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/hl6s7qfhwnghoaty2xq9r9d8xgoc34nurz.png)
![y + 1 = x + 1](https://img.qammunity.org/2021/formulas/mathematics/middle-school/fvhegmk1fc3kytme6c6migqcp6n8f1e64i.png)
