Question

point y(4, 3) is reflected across horizontal line y = 1. what will be the coordinates of y? (1 point)

Explanation:

Step1: Calculate vertical distance

The vertical distance between point $Y(4,3)$ and the line $y = 1$ is $d=3 - 1=2$.

Step2: Find new y - coordinate

When reflecting across the line $y = 1$, the x - coordinate remains the same. The new y - coordinate is $1-(3 - 1)=1 - 2=-1$.

Answer:

$(4,-1)$
