The task asks to reflect the points on the grid across the y-axis. When reflecting across the y-axis, the x-coordinate changes sign, while the y-coordinate remains the same.

Here are the steps to calculate the coordinates of the mirror points:

1. Identify the current coordinates of each point (A, B, C, etc.).
2. Reflect across the y-axis, changing the sign of the x-coordinates.

Let me start by listing the original coordinates of the points and then reflecting them.

Original Coordinates:

• A: (2, 1)
• B: (2, 2)
• C: (1, 2)
• D: (0, 2)
• E: (0, 1)
• F: (1, 1)
• G: (2, -3)
• H: (2, -2)
• I: (1, -2)
• J: (0, -3)
• K: (0, -1)
• L: (1, -1)
• M: (0, -2)
• N: (0, 0)

Reflected Coordinates (Mirror across y-axis):

• A' = (-2, 1)
• B' = (-2, 2)
• C' = (-1, 2)
• D' = (0, 2)
• E' = (0, 1)
• F' = (-1, 1)
• G' = (-2, -3)
• H' = (-2, -2)
• I' = (-1, -2)
• J' = (0, -3)
• K' = (0, -1)
• L' = (-1, -1)
• M' = (0, -2)
• N' = (0, 0)

If you need more details or have questions, feel free to ask!

Here are 5 related questions for practice:

1. What happens to coordinates when reflecting across the x-axis instead of the y-axis?
2. How would the coordinates change if the reflection was across the line $y = x$?
3. Can you reflect any shape across both the x- and y-axis? What would the final coordinates look like?
4. How do you reflect points across a line that is not vertical or horizontal, such as $y = -x$?
5. How would the coordinates of a point change if translated by a certain vector instead of reflecting?

Tip:

When reflecting a point over the y-axis, the y-coordinate stays the same, but the x-coordinate's sign is reversed. This is helpful to remember when reflecting any geometric shapes!
