Question

Find the coordinates of the vertices of each figure after a reflection over the given axis.

triangle ABC with vertices A(–8, 5), B(–7, –6), and C(3, 4); x-axis

Answer 1

A (-8, -5) , B (-7 , 6), C (3, -4)

Explanation:

A reflection over the y- axis changes the coordinates of the axis.

This ultimately changes the sign of the axis like this:

A(–8, 5), B(–7, –6), and C(3, 4)

the triangle will mapped into the coordinates:

A (-8, -5) , B (-7 , 6), C (3, -4)

Answer 2

see below

Explanation:

Reflection over the x-axis changes the sign of the y-coordinate without changing anything else. For example, ...

C(3, 4) becomes C'(3, -4) . . . . . sufficient to select the correct answer
