Reflections across Horizontal Lines

Which statements about reflections are true? Select all that apply.

Is the graph of x = 4 horizontal or vertical?

Reflect the point A(2, 3) over the line x = 2. 1) Graph the vertical line x = 2 using the line tool. 2) Plot the point (2, 3) 3) Use the "reflect about line" tool to reflect the point What is the location of the point A' ?

Reflect the point A(2, 3) over the line x = -4. 1) Graph the vertical line x = -4 using the line tool. 2) Plot the point (2, 3) 3) Use the "reflect about line" tool to reflect the point What is the location of the point A' ?

Reflect Triangle ABC over the line x = -1. Triangle ABC is located at A(-2, 2) B(1, 1) C(3, 5) 1) Graph the vertical line x = -1 using the line tool. 2) Plot the triangle using the polygon tool 3) Use the "reflect about line" tool to reflect the triangle What are the coordinates of A'B'C'?

Based on the previous problems, what observations do you have about reflecting points across any vertical line (x = #) ? Are there any similarities to reflecting over the y-axis (the y-axis is a vertical line)?
