A vertical plane mirror coincides with the yy-axis on a coordinate grid. A point source of light is placed at (−4 cm, 2 cm)(-4\,\text{cm},\,2\,\text{cm}). What are the coordinates of its image formed by the mirror? a) (4 cm, −2 cm)(4\,\text{cm},\,-2\,\text{cm}) b) (0 cm, 2 cm)(0\,\text{cm},\,2\,\text{cm}) c) (4 cm, 2 cm)(4\,\text{cm},\,2\,\text{cm}) d) (−4 cm, −2 cm)(-4\,\text{cm},\,-2\,\text{cm})
