The equation of the parallel line is y = –2x – 11.
Solution:
Given equation of the line is y = –2x – 5.
Slope of this line is
= –2
To write the equation parallel to this line and passes through (–4, –3).
If two lines are parallel, then they have the same slope.

Substitute the given values in the formula, we get
![y-(-3)=-2(x-(-4))](https://img.qammunity.org/2021/formulas/mathematics/middle-school/ilpuhkj73zlyiwbl1d7a1kvwqg3706notf.png)
![y+3=-2(x+4)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/b8st26f2g89r9piad6hefe89ioucm0b7xl.png)
![y+3=-2x-8](https://img.qammunity.org/2021/formulas/mathematics/middle-school/9d8ds4m8lvts0li7xgybmv5mz8zxv8qqnq.png)
Subtract 3 from both sides of the equation.
![y+3-3=-2x-8-3](https://img.qammunity.org/2021/formulas/mathematics/middle-school/x9ooy8f1nkbb3n3al1g0vp8b066p1y6z2n.png)
![y=-2x-11](https://img.qammunity.org/2021/formulas/mathematics/middle-school/um1qi7nqg0pk61cebobq6edclo8dkr7yf2.png)
Hence the equation of the parallel line is y = –2x – 11.
