The coordinates of A' are (8 , -5)
Step-by-step explanation:
Let us revise the reflection
- If point (x , y) reflected across the x-axis, then its image is (x , -y)
- If point (x , y) reflected across the y-axis, then its image is (-x , y)
- If point (x , y) reflected across the line y = x, then its image is (y , x)
- If point (x , y) reflected across the line y = -x, then its image is (-y , -x)
∵ Point A (-5 , 8) is reflected across the line y = x
∵ If point (x , y) reflected across the line y = x , then its image is (y , x)
∵ x = -5 and y = 8
- Switch x and y
∴ The image of point A is A' = (8 , -5)
The coordinates of A' are (8 , -5)
