What is the equation of the line of reflection that maps
the pre-image to the image?
y = x
y-axis
x-axis
x=1

y- axis

Step-by-step explanation:

Under a reflection in the y- axis

a point (x, y ) → (- x, y )

Consider the corresponding vertices

A(- 1, - 1 ) → A'(1, - 1 )

B(- 2, - 1 ) → B'(2, - 1 )

C(- 2, - 4) → C'(2, - 4 )

These coordinates satisfy the condition for reflection in the y- axis

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice
