(b) On the grid, draw the graph of \(y = 2x - 5\) for values of \(x\) from −2 to 4(2)
(c) Mark with a cross (×) a point on the grid that has coordinates satisfying both \[x \lt 2 \quad \text{and} \quad y \gt 2x - 5\]Label this point \(P\). (2)

Notes
M1: for a point marked above their line or for a point marked to the left of \(x = 2\)
A1: for a point marked above their line and marked to the left of \(x = 2\) (SC B1 for the correct region identified but no point plotted)
