Answer:
A reflection across the y axis
Step-by-step explanation:
think about it, if you reflect some point across the y-axis it will have a negative x value. For example, if you reflect (1,2) across the y-axis you will get (-1,2)
Answer:
This type of transformation is called mirroring in the y-axis.
Step-by-step explanation:
By mirroring in the y-axis, you can find the new value, by multiplying the x-coordinate by -1.
Any point (a , b) will be transformed after mirroring in the y-axis, to (-a , b), which is the question here.
This type of transformation is called mirroring in the y-axis.
