Triangle ABC has coordinates A(1, 4); B(3, –2); and C(4, 2). Find the coordinates of the image A'B'C' after a reflection over the x-axis

Answer 1

for a reflection over the x-axis, the x's stay the same, but the y's change to their opposites.

I will do point B
B(3,-2) ----> B' (3,2)

you do the rest.

I suggest to make a sketch to confirm what you did

Answer 2

a triangle has coordinates A(1,2),B(4,-2), and C(1,1) graph the triangle.
