Question

Point R, located at (-5, 3), is reflected over both axes. What are the coordinates of R'?

(-5, -3)
(5, -3)
(-5, 3)
(-3, 5)

Answer 1

reflection across both axices means from (x,y) to (-x,-y)
so

from (-5,3) turns to (5,-3)

Answer 2

`R'(x,y) = (5,-3)`

Explanation:

The reflection over both axes means that:

`R (x,y) = (x, y)` and
`R'(x,y) = (-x,-y)`

Then, the coordinates of R' are:

`R'(x,y) = (5,-3)`
