Question

list the coordinates of the figure. then list the coordinates after a reflection over the x - axis. r: b: y: r: b: y: 90° ccw or 270° cw

Explanation:

Step1: Determine original coordinates

Count the grid - squares to find the coordinates of points R, B, and Y. For a point (x,y) on a coordinate - grid, x is the horizontal displacement from the origin and y is the vertical displacement.
R: (0, 1), B: (8, 7), Y: (7, 2)

Step2: Apply reflection rule over x - axis

The rule for reflecting a point (x,y) over the x - axis is (x, - y).
For point R(0, 1), after reflection R'(0, - 1).
For point B(8, 7), after reflection B'(8, - 7).
For point Y(7, 2), after reflection Y'(7, - 2).

Answer:

R: (0, 1)
B: (8, 7)
Y: (7, 2)
R': (0, - 1)
B': (8, - 7)
Y': (7, - 2)
