Answer:
The coordinates of A'' are (-2 , -5) ⇒ answer A
Step-by-step explanation:
* Lets revise some transformation
- If point (x , y) reflected across the x-axis
∴ Its image is (x , -y)
- If point (x , y) reflected across the y-axis
∴ Its image is (-x , y)
- If point (x , y) reflected across the line y = x
∴ Its image is (y , x)
- If point (x , y) reflected across the line y = -x
∴ Its image is (-y , -x)
* Now lets solve the problem
- The vertices of triangle ABC are:
A is (2 , -5) , B is (1 , -3) , C is (5 , -3)
∵ The triangle is reflected across the y-axis
∴ The x- coordinates of the three point are changed to opposite sign
∵ A is (2 , -5)
∴ its image A" is (-2 , -5)
* The coordinates of A'' are (-2 , -5)
