Answer:
(1, -1)
Step-by-step explanation:
Reflecting over the y-axis means
[tex](x,y) \longrightarrow (-x,y)[/tex]
So,
[tex]R(-1,-1) \longrightarrow (1,-1)[/tex]
The coordinates of R' is given as (1,-1)
Coordinates of point R is given as (-1,-1) and it is required to find the Coordinates of reflection of R about y-axis.
What is reflection in coordinate geometry ?
this represents the flip or mirror image of transformation about the given axis.
Thus, the given point R is in 3rd quadrant and its mirror image will be in 4th
quadrant with Coordinates R' as (1,-1). Graphical representation id given below.
