<u>Answer-</u>

<em>The coordinates of D' are (-1, </em><em>-5</em><em>)</em>

<u>Solution-</u>

The coordinates of D are (-1, 5).

While reflecting any points across the x-axis with coordinates as (x, y) becomes, (x, -y). i.e sign of y-coordinate changes.

The rule is (x, y) → (x, -y)

Applying so, after reflecting point D, its reflection D' will have coordinates as (-1, -5)

Therefore, the y-coordinate is -5.

A bottle of water - 60p

A bag of crisp - 85p
