Answer:The coordinates of the resulting point after the reflection across the y - axis will be P'(3, 2).
What do you mean by reflection of coordinates?
A reflection on the coordinate plane is a type of transformation. It takes a geometric figure such as a point, line segment, or shape and transforms it into a congruent geometric figure called the image.
Given is a point (-3, 2) reflected across the y - axis.
Now, when any given coordinate is reflected across the y - axis then, the sign of the x - coordinate is inverted and the y - coordinate remains same.
As given, the coordinates of the point are - P(-3, 2)
Now, after reflection across the y - axis, the new coordinates of the image of this point will be -
x' = - (- 3) = 3
y' = y = 2
P'(3, 2)
Therefore, the coordinates of the resulting point after the reflection across the y - axis will be P'(3, 2)
