Answer:
(K'(- 1, - 2 )
Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y ) → (x, - y )
Thus
K(- 1, 2 ) → K'(- 1, - 2 )
K=(-1,2) -> (-1,-2) because it will be crossing the x axis which will change the position of the point making it both negative because it will be in a new axis
