The equation provided is $y = -2x - 1$. You are asked to complete the table with missing values for $y$ corresponding to different values of $x$.

Let's substitute the given $x$ values into the equation $y = -2x - 1$ to find the missing values:

1. For $x = -2$: $y = -2(-2) - 1 = 4 - 1 = 3$ So the value for $y$ when $x = -2$ is 3, which matches the table.

2. For $x = -1$ (finding A): $y = -2(-1) - 1 = 2 - 1 = 1$ So, $A = 1$.

3. For $x = 0$ (finding B): $y = -2(0) - 1 = 0 - 1 = -1$ So, $B = -1$.

4. For $x = 1$: $y = -2(1) - 1 = -2 - 1 = -3$ This matches the table.

5. For $x = 2$ (finding C): $y = -2(2) - 1 = -4 - 1 = -5$ So, $C = -5$.

The completed table is:
