R (3, 2), S (5, -2), and T (6, 0) are the coordinates of a triangle's vertices. If the triangle is reflected over the y-axis, what are the coordinates of the image?


R'(-3, 2), S'(-5, -2), T'(6, 0)

R'(-3, 2), S'(-5, -2), T'(-6, 0)

R'(-3, -2), S'(-5, 2), T'(-6, 0)

R'(3, -2), S'(5, 2), T'(6, 0)

Answer 1

If the triangle is reflected the new coordinate will be

R'(-3, 2), S'(-5, -2), T'(-6, 0)

Answer 2

• B. R'(-3, 2), S'(-5, -2), T'(-6, 0)

Explanation:

Reflected over the y-axis changes x-coordinate to opposite and y-coordinate remains as is:

• (x, y) → (-x, y)

Apply the rule to the given points:

• R (3, 2) → R'(-3, 2)
• S (5, -2) → S'(-5, -2)
• T (6, 0) → T'(-6, 0)

Correct option is B
