Answer:
K(1,0), L(2, 3), M(-1, 4), N(-2,1)
Explanation:
Because the points are being flipped over the x-axis the y values remain the same, but the x values are multiplied by -1. Multiplying the values by -1 will switch a negative value positive and a positive value negative. This will correctly flip the points to the opposite side of the graph.
