Certainly. It could, for example, be a power relationship such as y = x^3
It is sometimes true that a scatter plot showing a positive association suggests a proportional relationship, but not always. A positive association indicates that as one variable increases, the other tends to increase as well, but the relationship may not be linear or proportional. Proportional relationships require that the ratio of the two variables remains constant, which is not guaranteed by a positive association alone. Therefore, while some positively associated relationships can be proportional, others may not be.
None.

A correlation exists in a scatter plot if there is a general trend in the outputs as inputs increase. If the outputs generally increase in value, then there is a positive correlation. If the outputs generally decrease in value, then there is a negative correlation.
An example of a positive correlation is: the number of cars on the road and the number of greenhouse gas emissions there are. As one of those rises, so does the other. A negative correlation is when one statistic rises causing the other to drop. Look at a few scatter plots and you will easily be able to see positive and negative correlations
To accurately describe the type of relationship shown by a scatter plot, I would need to see the plot itself. Generally, scatter plots can depict various relationships such as positive, negative, or no correlation. A positive relationship indicates that as one variable increases, the other also increases, while a negative relationship shows that as one variable increases, the other decreases. If the points are randomly scattered without any discernible pattern, it suggests no correlation.
Positive correlation = the slope of the scattered dots will rise from left to right (positive slope) Negative correlation = the slope of the scattered dots will fall from left to right (negative slope) No correlation = no real visible slope, the dots are too scattered to tell.
Yes, it is possible to draw a trendline on a scatter plot that shows no association. In such cases, the trendline may be flat or have a very shallow slope, indicating that there is no significant relationship between the variables. However, the presence of a trendline does not imply a meaningful correlation; it merely represents a statistical fit to the data points, which may be scattered randomly without any discernible pattern.
A trend that decreases downward in a scatter plot.
you graph the points going downwards
negative
If Y increases as X increases, you are referring to a positive correlation. However, if Y falls as X increses, you have a negative correlation.
