Reflections Across the Line y = 1

Mr. Deadly provides a tutorial on graphing reflections, focusing on reflecting shapes across the line y = 1. He explains how to plot points and establish a mirror line, then demonstrates how to reflect points over this line. The lesson concludes with a verification of the reflections to ensure accuracy.

What is the main topic of the worksheet discussed in the video?

• Graphing reflections

• Graphing translations

• Graphing rotations

• Graphing dilations

Which axis is commonly used for basic reflections in graphing?

• z-axis

• y-axis

• w-axis

• x-axis

What does the line y = 1 represent in the context of reflections?

• A diagonal line

• A vertical line

• A curved line

• A horizontal line

What is the y-coordinate of any point on the line y = 1?

• 3

• 2

• 1

• 0

What is the purpose of drawing a line at y = 1 in the context of this lesson?

• To serve as a new axis

• To act as a mirror line for reflections

• To mark the origin

• To divide the graph into two halves

What is the role of the line y = 1 in the reflection process?

• It is used to measure angles

• It divides the graph into quadrants

• It serves as a mirror line

• It acts as a new x-axis

If a point is 3 units above the line y = 1, where should it be reflected?

• 1 unit below the line

• 2 units below the line

• 4 units below the line

• 3 units below the line

What is the first step in reflecting a point across the line y = 1?

• Move the point to the origin

• Count the distance from the point to the line

• Draw a new line parallel to y = 1

• Rotate the point 90 degrees

What happens to a point on the line y = 1 when it is reflected across the same line?

• It stays in the same place

• It disappears

• It moves to the origin

• It moves to the x-axis

Which of the following is NOT a step in reflecting a point across y = 1?

• Ensure the distance is equal on both sides

• Change the x-coordinate of the point

• Move the point to the opposite side of the line

• Identify the distance from the point to the line
