Question

write the coordinates of the vertices after a reflection over the x-axis.
k(□, □)
l(□, □)
m(□, □)
n(□, □)

Explanation:

Step1: Identify original coordinates

Original vertices: K(-1,-9), L(5,-9), M(5,0), N(-1,0)

Step2: Apply reflection over x-axis

Rule: (x,y)→(x,-y). So:
K'(-1,9), L'(5,9), M'(5,0), N'(-1,0)

Answer:

K'(-1, 9), L'(5, 9), M'(5, 0), N'(-1, 0)
