Find K' if the figure is reflected across the x-axis

Explanation:
Point K is located at (1, -4)
We use the rule that [tex](x,y) \to (x,-y)[/tex] when reflecting over the x axis.
The x coordinate stays the same, but the y coordinate flips from positive to negative or vice versa.
Therefore, K(1,-4) will move to K ' (1, 4)
