Question

Reflect all of the coordinates from the previous slide over the y-

axis and state the coordinates below.
(0,2)
(-3,2)
(-6,3)
(-6,9)
(-3,12)
(0,12)
New X
New Y

Answer 1

To reflect coordinates over the y-axis, change the sign of the x-coordinate. Points on the y-axis remain unchanged after reflection.

Step-by-step explanation:

To reflect coordinates over the y-axis, you must change the sign of the x-coordinate while keeping the y-coordinate the same. The reflection of a point across the y-axis follows the rule (x, y) becomes (-x, y). Applying this rule:

• (0,2) becomes (0,2)
• (-3,2) becomes (3,2)
• (-6,3) becomes (6,3)
• (-6,9) becomes (6,9)
• (-3,12) becomes (3,12)
• (0,12) becomes (0,12)

Note that points on the y-axis (x=0) do not change upon reflection over the y-axis.
