Question

Point P' is the image of P(3,5) under a reflection across the y-axis.
What are the coordinates of P'?

Answer 1

Answer:

(-3,5)

Step-by-step explanation:

In reflections the x axis is the opposite only

Answer 2

When a point is reflected, it must be reflected across a line

The coordinates of point P' are (-3,5)

The rule of reflection across the y-axis is:

$(x,y) \to (-x,y)$

The coordinates of point P is given as:

$P = (3,5)$

So, we have:

$(3,5) \to (-3,5)$

Hence, the coordinates of point P' are (-3,5)
