Answer:
Rx-axis (P) is (-4 , 1)
Explanation:
* Lets revise the reflection
- 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)
* Lets solve the problem
∵ The point P is (-4 , -1)
∵ Rx-axis (P) means reflect point P across the x-axis
∵ The reflection of a point (x , y) across the x-axis is (x , -y)
- That means we will change the sign of the y-coordinate of point P
∵ P = (-4 , -1)
∴ The y-coordinate of point P is -1 will change to 1
∴ The image of point P after reflection is (-4 , 1)
* Rx-axis (P) is (-4 , 1)
