Reflecting a point over the x-axis
• Change the y-coordinate to its opposite.
Example:Plot (-2, 3) and its reflection across the x-axis.
Coordinates of reflection: (-2, -3)
Reflecting a point over the y-axis
• Change the x-coordinate to its opposite.
Example:Plot (6, 2) and its reflection across the y-axis.
Coordinates of reflection: (-6, 2)
Examples:
a) If (-7, -1) is reflected over the x-axis, what would be its new coordinates?
b)If (3, -10) is reflected over the y-axis, what would be its new coordinates?
Henry plotted point X at (-3, 6). He then reflected this point over the x-axis and labeled this point Y. Then he reflected Point Y over the y-axis to get point Z. What is the ordered pair for point Z?
Point Y: ______Point Z: ______
Let’s Review!!!• How are the coordinates of a point affected by a
reflection of the point over the x-axis?
The y-coordinate changes to its opposite.
• How are the coordinates of a point affected by a reflection of the point over the y-axis?
The x-coordinate changes to its opposite.
