Question

The point (2, -5) is reflected over the y-axis. Which of the following points is the image?

Answer 1

(-2, -5)

Explanation:

A reflection over the y-axis would be (-x, y). We are given the point (2, -5), so to reflect this point over the y-axis you would make the x-value negative and keep the y-value the same.

(2, -5) --> (-2, -5)

Answer 2

The image of (2,-5) after reflected over the y-axis is (-2,-5)

Explanation:

we are given a point as (2,-5)

and it is reflected about y-axis

Suppose, we have a point as (a,b)

and it is reflected about y-axis

we can replace 'a' as -a

so, point changes after reflection as

(a,b)------>(-a,b)

now, we have point as (2,-5)

x-value is 2

so, 2 changes to -2

so, point after reflection is (-2,-5)
