### Correlation and Scatterplots Matching Exercise

#### Instructions:
Match these values of \( r \) with the accompanying scatterplots: 0.42, -0.781, -1, 1, and 0.995. Click the icon to view the scatterplots.

#### Options:
Match the values of \( r \) to the scatterplots.

- Scatterplot 1, \( r \) = 
- Scatterplot 2, \( r \) = 
- Scatterplot 3, \( r \) = 
- Scatterplot 4, \( r \) = 
- Scatterplot 5, \( r \) = 

#### Scatterplot Details:

##### Scatterplot 1:
- **Description:** A graph with 10 points that show a perfect positive linear relationship, rising from the bottom left to the top right. 
- **Axes:** `x` ranges from 0 to 1; `y` ranges from 10 to 15.

##### Scatterplot 2:
- **Description:** A graph with 10 points indicating a moderate positive linear relationship, rising from the bottom left but with more variance than Scatterplot 1.
- **Axes:** `x` ranges from 0 to 1; `y` ranges from 0 to 8.

##### Scatterplot 3:
- **Description:** A graph with 10 points showing no apparent linear relationship, with points scattered randomly.
- **Axes:** `x` ranges from 0 to 1; `y` ranges from 0 to 8.

##### Scatterplot 4:
- **Description:** A graph with 10 points that show a perfect negative linear relationship, descending from the top left to the bottom right. 
- **Axes:** `x` ranges from 0 to 1; `y` ranges from -4 to 4.

##### Scatterplot 5:
- **Description:** A graph with 10 points indicating a strong positive linear relationship, with points closely clustered around a positively sloped line but with slight variance.
- **Axes:** `x` ranges from 0 to 1; `y` ranges from 0 to 8.

#### Matching Values of \( r \):
Based on the appearances of the scatterplots, match each scatterplot with the appropriate value of the correlation coefficient \( r \):

- \( r = 0.42 \)
- \( r = -0.781 \)
- \( r = -1
