Answer:
N (-1, -2), L (-3, 2), M (0, 4)
Step-by-step explanation:
When a point is reflected over the x-axis, the y value simply becomes negative when it was positive, and vise-versa.
The y-values of N', L', and M' are 1, 3, and 0, respectively.
If they become negative, they are now -1, -3, and 0.
The x- values stay the same, which are -2, 2, and 4.
Their original coordinates are (-1, -2), (-3, 2), and (0, 4)
