Question

point a has coordinate a(3, 2). the point is rotated 180° clockwise about the origin. what is the x-coordinate of point a? ( enter one corrdinate point only )

Explanation:

Step1: Recall 180° rotation rule

For a point $(x,y)$ rotated $180^\circ$ about the origin, the new coordinates are $(-x,-y)$.

Step2: Apply rule to A(3,2)

Substitute $x=3$, $y=2$ into the rule: $(-3, -2)$.

Step3: Identify x-coordinate

The x-coordinate of the new point is $-3$.

Answer:

$-3$
