Question

Triangle IJK has the coordinates listed:
Where is J' after a reflection over the y-axis?

Answer 1

(-10, -8)

Explanation:

The rule for a reflection over the y -axis is (x, y)→(−x, y) .

so J(10, -8) becomes J'(-10, -8)

Answer 2

J' (- 10, - 8 )

Explanation:

Under a reflection in the y- axis

a point (x, y ) → (- x, y ) , then

J (10, - 8 ) → J' (- 10, - 8 )
