(a(i))[2]
Sketch the line $x + y + 2 = 0$ on the grid.
(a(ii))[2]
Region $R$ is described by the three inequalities below: $2y \ge x + 4$, $x + y + 2 \ge 0$, $y \le 2$. Shade this area on the grid and label it $R$.
(b)[3]
Line $L$ is perpendicular to the line $2y = x + 4$ and passes through the point $(1, 8)$. Show that the equation of line $L$ is $y = 10 - 2x$.
(c)[3]
Use an algebraic method to determine the coordinates where the lines $2y = x + 4$ and $y = 23 - 2x$ meet.
