Question

rotate point b 180° counter - clockwise about the origin. enter the new coordinates. b=(?,)

Explanation:

Step1: Recall rotation rule

The rule for rotating a point $(x,y)$ 180° counter - clockwise about the origin is $(x,y)\to(-x,-y)$.

Step2: Apply rule to point B

Given point B$(4,2)$, where $x = 4$ and $y = 2$. After applying the rule, we get $x'=-4$ and $y'=-2$.

Answer:

$(-4,-2)$
