Question

3) Rotate counterclockwise around the origin180°180°Ay41NН.2.4xK44What is the rule? (x,y) - (___)H(__)l'(_,J'(___)K'(__)

Answer 1

We have the next points

H(-4,1)

I(-2,2)

J(-1,-2)

K(-4,-4)

The rule to rotate 180° counterclockwise

$(x,y)\rightarrow(-x,-y)$

with rule, we can find the points

H'=(-(-4),-1)=(4,-1)

I'=(-(-2),-2)=(2,-2)

J'=(-(-1),-(-2))=(1,2)

K'=(-(-4),-(-4))=(4,4)

so the answer is

H'=(4,-1)

I'=(2,-2)

J'=(1,2)

K'=(4,4)

we can graph them they are the points in red
