What are the coordinates of the vertices of the image?
anyone who is amazing at maths please help!!!!!!!!!!!!!!!!!!!!
i am running out of time

Answer 1

reflected image shown in red on attached diagram

Explanation:

When reflecting an object in the line x = a:

• reflected x-values: 2a - x
• reflected y-values are the same as the original y-values

So when reflecting in the line x = 1

• given x-value = 2, so reflected x-value = 2(1) - 2 = 0
• given x-value = 4, so reflected x-value = 2(1) - 4 = -2

(2, 7) → (0, 7)

(2, 4) → (0, 4)

(4, 4) → (-2, 4)
