Consider any point P(x, y) in the coordinate axis.

The reflection of this point across the y-axis is the point P'(-x, y).

(x, y) and (-x, y) are the 'mirror' images of each other, with the y'axis as the 'mirror'.

For example the coordinates of the image of P(4, 13) after the reflection across the y-axis is P'(-4, 13)

or, if P(-5, -9), then P'(5, -9)


Answer: if coordinates of V are (h, k), coordinates of V' are (-h, k)

Ira Lisetskai [31]
10w + 4w = - 84
14w = - 84
w = - 84 : 14
w = - 6  (  answer )
-----------------------------------
10 * (- 6) + 4 * (- 6) = - 84
            - 60 + (- 24) = - 84
                         - 84 = - 84
