Question

Point R is located at (-1,-1) on the coordinate plane. Point R is reflected over the

y-axis to create point R'. What ordered pair describes the location of R'?

Answer 1

Answer: (1,-1)

Reason:

The y axis reflection rule to use is
`(\text{x},\text{y}) \to (-\text{x}, \text{y})`

It says to flip the sign of the x coordinate. The y coordinate stays the same.

Therefore, the point (-1,-1) reflects over the y axis to land on (1,-1)
