Question

write the coordinates of the vertices after a reflection over the x - axis.

Explanation:

Step1: Recall reflection rule

For reflection over x - axis, $(x,y)\to(x, - y)$.

Step2: Find new coordinates of E

E is at $(1,-3)$, after reflection E' is $(1,3)$.

Step3: Find new coordinates of F

F is at $(3,-3)$, after reflection F' is $(3,3)$.

Step4: Find new coordinates of G

G is at $(2,-7)$, after reflection G' is $(2,7)$.

Answer:

E'(1,3), F'(3,3), G'(2,7)
