The coordinates of A' are (-5,-3).
What are coordinates?
- A coordinate system in geometry is a system that uses one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.
- The order of the coordinates matters and they are sometimes identified by their position in an ordered tuple, and other times by a letter, as in "the x-coordinate."
- In elementary mathematics, the coordinates are assumed to be real numbers, but they can also be complex numbers or members of a more abstract system, such as a commutative ring.
- The use of a coordinate system allows geometry issues to be transformed into numerical problems and vice versa; this is the foundation of analytic geometry.
Solution -
If AABC is reflected across the y-axis, the coordinates of A' are (-5,-3).
The reflected graph is given below.
Therefore, the coordinates of A' are (-5,-3).
