Answer:
1. Plot the points on the graph and join them to create the pool (see attachment).
With the points, the first number is the x-value and the second number is the y-value. For example, for point A(1, 2) this would be x = 1 and y = 2. The x-axis is the horizontal axis and the y-axis is the vertical axis. Where the two axis cross, this point is (0, 0) or the origin.
Quadrant 1 is the upper right quadrant where x>0 and y>0
2. Reflect over the y-axis. All the x-coordinates of the points will become negative and the y-coordinates of the points will stay the same.
A'(-1, 2)
B'(-2, 6)
C'(-7, 8)
D'(-9, 3)
3. Rotated 90 degrees clockwise about (0, 0)
Swap the x and y coordinates and make the y coordinate negative:
A''(2, -1)
B''(6, -2)
C''(8, -7)
D''(3, -9)
4. Reflect the image in quadrant 4 across the y-axis. The shape drawn in question 3 is in quadrant 4. So this needs to be reflected across the y-axis. Same coordinates as those in question 3, but the x-coordinate needs to be negative.
A'''(-2, -1)
B'''(-6, -2)
C'''(-8, -7)
D'''(-3, -9)
