Shape $P$ is a triangle with vertices $(1, 1)$, $(4, 1)$ and $(1, 3)$. A single enlargement maps $P$ onto triangle $Q$, whose vertices are $(7, 7)$, $(1, 7)$ and $(7, 3)$, with $(1, 1)$ mapping to $(7, 7)$. The same enlargement (same centre, same scale factor) is now applied to $Q$ to give triangle $R$. What are the coordinates of the vertex of $R$ that comes from $(7, 7)$?

• A$(11, 11)$
• B$(-2, -2)$
• C$(-5, -5)$
• D$(-1, -1)$
