Based on the information provided, the scatterplot represents:
- Bivariate: This is because there are two variables being examined (temperature and elevation).
- Non-linear relationship: Since you have only provided a single point (-2, -3), it does not imply a linear relationship. Usually, a further description or more points would be needed to definitively confirm the relationship type, but with just one point, we lean towards non-linear.
- Decreasing: If we assume that the relationship between temperature and elevation typically shows that as temperature decreases, elevation may increase or vice versa, one could interpret a decreasing trend (if we were to expect a negative correlation). However, more context would be required to firmly support this.
So, the three selections would be Bivariate, Non-linear relationship, and potentially Decreasing based on the typical relationship assumptions. However, if we strictly consider what's given (just one data point), it may be more accurate to only confidently choose the first two.
