Given points P(2, 9), Q(6, 3), R(2, -3), and S(-4, 3), and the equation y = 1/2x + 3, plot the points and graph the equation.

• Point P is at $(2, 9)$.
• Point Q is at $(6, 3)$.
• Point R is at $(2, -3)$.
• Point S is at $(-4, 3)$.

The coordinates are:
P: $\boxed{(2, 9)}$
Q: $\boxed{(6, 3)}$
R: $\boxed{(2, -3)}$
S: $\boxed{(-4, 3)}$

• For $x = -4$: $$y = \frac{1}{2}(-4) + 3 = -2 + 3 = 1$$
• For $x = -2$: $$y = \frac{1}{2}(-2) + 3 = -1 + 3 = 2$$
• For $x = 0$: $$y = \frac{1}{2}(0) + 3 = 0 + 3 = 3$$
• For $x = 2$: $$y = \frac{1}{2}(2) + 3 = 1 + 3 = 4$$
• For $x = 4$: $$y = \frac{1}{2}(4) + 3 = 2 + 3 = 5$$

The completed table is:

Plot the points from the table: $(-4, 1)$, $(-2, 2)$, $(0, 3)$, $(2, 4)$, and $(4, 5)$.
Draw a straight line connecting these points. The graph drawn on the provided grid correctly represents these points and the line.
