Question

axis of reflection y = 1 x (1,-1) y (4,3) z (6,0) what are the coordinates of y after a reflection across y = 1? (1 point)

Explanation:

Step1: Find the distance from point Y to the line y = 1

The y - coordinate of point Y is 3 and the line of reflection is y = 1. The distance is $d=3 - 1=2$.

Step2: Calculate the new y - coordinate

For a reflection over the line y = 1, the x - coordinate of the point remains the same. The new y - coordinate is $1-(3 - 1)=1 - 2=-1$. The x - coordinate of Y is 4. So the coordinates of Y' are (4, - 1).

Answer:

(4, - 1)
