Question

Given ABCD with A = (1,1), B = (4, 2), C = (4, 5), and D = (1, 4), what are the coordinates for Point C' if the y-axis is the reflecting line?

Answer 1

• (- 4, 5)

===============

The rule for a reflection in the y-axis is:

• (x, y) → (- x, y)

Apply the rule to the point C:

• C → C'
• (4, 5) → (- 4, 5)
