Answer:
The location of Huang's house is (5,2)
Explanation
We can see in the picture that
Elm street can be defines as x-axis
Oak street cab be defines as y-axis
A reflection can be defined as flipping an object over the line of reflection. The original object is called pre-image, and the newly formed reflection is called image. Both the object and reflection have the same size and shape, and same distance from the line of reflection.
E.g when reflecting an object across x-axis , the x-coordinate of the object remains the same in the reflection, but the sign of y-coordinate is changed.
Similarly, when reflecting an object across y-axis, y-coordinate of the object remains the same in reflection, but the sign of x-coordinate is changes.
In the question, the location of Vijay's house is given by coordinates (-5,2)
As we can consider Oak street as y-axis, and we have to reflect the house across Oak street, then the reflection will have same y-coordinates, but the sign of x coordinate will change.
Which means the location of Huang's house is (5,2)
