Given the equation y = 2x − 7 and one point (2, -3), complete the table of values.

For the second row, $x = 0$:

$$y = 2(0) - 7$$ $$y = 0 - 7$$ $$y = -7$$

For the third row, $y = 0$:

$$0 = 2x - 7$$ $$7 = 2x$$ $$x = \frac{7}{2}$$ $$x = 3.5$$

For the fourth row, since no value is given, we can choose a simple integer for $x$, for example, $x = 1$:

$$y = 2(1) - 7$$ $$y = 2 - 7$$ $$y = -5$$

The completed table is:

$$\begin{array}{|c|c|} \hline x & y \\ \hline 2 & -3 \\ \hline 0 & -7 \\ \hline 3.5 & 0 \\ \hline 1 & -5 \\ \hline \end{array}$$

The completed table is $\boxed{\begin{array}{|c|c|} \hline x & y \\ \hline 2 & -3 \\ \hline 0 & -7 \\ \hline 3.5 & 0 \\ \hline 1 & -5 \\ \hline \end{array}}$.
