Question

rotations
find d after $r_{180^{\circ}}(x,y)=(-x,-y)$.
$d = (?, \\ \\ \\ )$

Explanation:

Step1: Identify coordinates of D

From the graph, $D=(9, 7)$

Step2: Apply 180° rotation formula

Use $r_{180^\circ}(x,y)=(-x,-y)$. Substitute $x=9, y=7$:
$D' = (-(9), -(7)) = (-9, -7)$

Answer:

$(-9, -7)$
