Question

question what is the image of the point (1, 8) after a rotation of 180° counterclockwise about the origin? answer attempt 1 out of 2

Explanation:

Step1: Recall rotation rule

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

Step2: Apply the rule

For the point $(1,8)$, when $x = 1$ and $y = 8$, we have $-x=-1$ and $-y = - 8$.

Answer:

$(-1,-8)$
