Step1: Identify original point N
Original coordinates of $N$: $(-1, -2)$
Step2: Apply 270° CCW rotation rule
Rule: $(x,y)\to(y,-x)$
$N' = (-2, -(-1)) = (-2, 1)$

Step1: Identify original point T
Original coordinates of $T$: $(5, 3)$
Step2: Apply 180° rotation rule
Rule: $(x,y)\to(-x,-y)$
$T' = (-5, -3)$
---
Step1: Identify original point G
Original coordinates of $G$: $(-3, 4)$
Step2: Apply 90° CCW rotation rule
Rule: $(x,y)\to(-y,x)$
$G' = (-4, -3)$
---
Step1: Identify original point A
Original coordinates of $A$: $(2, 1)$
Step2: Apply 90° clockwise rotation rule
Rule: $(x,y)\to(y,-x)$
$A' = (1, -2)$
---
Step1: Apply 180° rotation inverse rule
Rule for inverse: $(x',y')\to(-x',-y')$
$P = (-8, -(-2)) = (-8, 2)$
---
Step1: Apply 90° CCW rotation inverse rule
Inverse rule: $(x',y')\to(y',-x')$
$M = (-4, -(-5)) = (-4, 5)$
