(2,-8)

Step-by-step explanation

The rule for a rotation by 180° about the origin is:


(x,y)\Rightarrow(-x,-y)

in other words you have to change the sign of x component and y component, so


(-2,8)\Rightarrow rotated\text{ 180 \degree}\Rightarrow(-(-2),-(8))=(2,-8)

so, the point that results is

(2,-8)

I hope this helps you
