Answer:

C' = -10,2

D' = -1,6

E' = -10,2

Answer:

see explanation

Step-by-step explanation:

Under a reflection in the vertical line x = - 1 the y- coordinates remain unchanged.

The points and their images will be the same distance from x = - 1

The original points are to the left and the image points to the right.

C (- 10, - 6 ) is 9 units to the left of x = - 1 , then

C' (- 1 + 9, - 6 ) → C' (8, - 6 ) ← 9 units right

D (- 1, - 6 ) is on the line of reflection and remains unchanged

D (- 1, - 6 ) → D' (- 1, - 6 )

E (- 10, - 2 ) → E' (- 1 + 9, - 6 ) → E' (8, - 2 )

Then

C (- 10, - 6 ) → C' (8, - 6 )

D (- 1, - 6 ) → D' (- 1, - 6 )

E (- 10, - 2 ) → E' (8, - 2 )
