1. The problem is to find the missing value of $y$ when $x = -1$ in the equation $y - 3 = 2(x + 1)$. 2. The formula given is a linear equation in point-slope form. We will substitute $x = -1$ and solve for $y$. 3. Substitute $x = -1$ into the equation: $$y - 3 = 2(-1 + 1)$$ 4. Simplify inside the parentheses: $$y - 3 = 2(0)$$ 5. Multiply: $$y - 3 = 0$$ 6. Add 3 to both sides to isolate $y$: $$y = 3$$ 7. Therefore, the missing value is $3$. The complete point is $(-1, 3)$.
