Answer :
To solve this task, we need to find the average of the x-coordinates and y-coordinates for each set of given points. Here's a step-by-step breakdown of how you can find these averages for each set:
### Set 1: [tex]\(\{(2,-2),(1,5),(-2,2),(1,-3),(8,-1)\}\)[/tex]
1. Identify the x-coordinates: 2, 1, -2, 1, 8
2. Identify the y-coordinates: -2, 5, 2, -3, -1
Calculate the average x-coordinate:
[tex]\[ \text{Average } x = \frac{2 + 1 - 2 + 1 + 8}{5} = \frac{10}{5} = 2.0 \][/tex]
Calculate the average y-coordinate:
[tex]\[ \text{Average } y = \frac{-2 + 5 + 2 - 3 - 1}{5} = \frac{1}{5} = 0.2 \][/tex]
So, the average for Set 1 is [tex]\((2.0, 0.2)\)[/tex].

### Set 2: [tex]\(\{(3,-1),(7,1),(-6,-1),(9,1),(2,-1)\}\)[/tex]
1. Identify the x-coordinates: 3, 7, -6, 9, 2
2. Identify the y-coordinates: -1, 1, -1, 1, -1
Calculate the average x-coordinate:
[tex]\[ \text{Average } x = \frac{3 + 7 - 6 + 9 + 2}{5} = \frac{15}{5} = 3.0 \][/tex]
Calculate the average y-coordinate:
[tex]\[ \text{Average } y = \frac{-1 + 1 - 1 + 1 - 1}{5} = \frac{-1}{5} = -0.2 \][/tex]
So, the average for Set 2 is [tex]\((3.0, -0.2)\)[/tex].

### Set 3: [tex]\(\{(6,8),(5,2),(-2,-5),(1,-3),(-2,9)\}\)[/tex]
1. Identify the x-coordinates: 6, 5, -2, 1, -2
2. Identify the y-coordinates: 8, 2, -5, -3, 9
Calculate the average x-coordinate:
[tex]\[ \text{Average } x = \frac{6 + 5 - 2 + 1 - 2}{5} = \frac{8}{5} = 1.6 \][/tex]
Calculate the average y-coordinate:
[tex]\[ \text{Average } y = \frac{8 + 2 - 5 - 3 + 9}{5} = \frac{11}{5} = 2.2 \][/tex]
So, the average for Set 3 is [tex]\((1.6, 2.2)\)[/tex].

### Set 4: [tex]\(\{(-3,1),(6,3),(-3,2),(-3,-3),(1,-1)\}\)[/tex]
1. Identify the x-coordinates: -3, 6, -3, -3, 1
2. Identify the y-coordinates: 1, 3, 2, -3, -1
Calculate the average x-coordinate:
[tex]\[ \text{Average } x = \frac{-3 + 6 - 3 - 3 + 1}{5} = \frac{-2}{5} = -0.4 \][/tex]
Calculate the average y-coordinate:
[tex]\[ \text{Average } y = \frac{1 + 3 + 2 - 3 - 1}{5} = \frac{2}{5} = 0.4 \][/tex]
So, the average for Set 4 is [tex]\((-0.4, 0.4)\)[/tex].
Hence, the averages for the four sets of points are:
[tex]\[ ((2.0, 0.2), (3.0, -0.2), (1.6, 2.2), (-0.4, 0.4)) \][/tex]
These are the average coordinates for each set of points provided.
