Question

list the coordinates of the figure. then list the coordinates after a reflection over the y - axis.

Explanation:

Step1: Determine original coordinates

Count grid - squares. R is at (4, 1), B is at (1, 5), Y is at (0, 0).

Step2: Apply reflection rule over y - axis

The rule for reflecting a point (x, y) over the y - axis is (-x, y).
For R(4, 1), R' is (-4, 1).
For B(1, 5), B' is (-1, 5).
For Y(0, 0), Y' is (0, 0).

Answer:

R: (4, 1)
B: (1, 5)
Y: (0, 0)
R': (-4, 1)
B': (-1, 5)
Y': (0, 0)
