randomness of data
line of fit
Not necessarily. In a scatter plot or regression they would not.
a scatter plot is a piece of data that shows you how to make a prediction
You can have any two variables. In fact, you can also have just one variable over two points in time - for example, a scatter plot of the price of something plotted against the price of the same thing a year earlier.
You can have a line of best fit. It is the line that cuts through the points with the least amount of distance to all the data.

If ( x ) increases and ( y ) decreases, this relationship is shown on a scatter plot as a downward slope from left to right. The points will trend downward, indicating that as the values of ( x ) rise, the corresponding values of ( y ) fall. This pattern reflects a negative correlation between the two variables.
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.

Scatter plot
There is no such thing as a general pattern. Depending on the variables and the relationship between them, you can have points all over the plot, exactly on a straight line or a curve, or close to such a line or curve.
A scatter plot that shows no correlation displays points that are randomly distributed without any discernible pattern, indicating that there is no relationship between the two variables. In contrast, a scatter plot that shows a negative correlation features points that trend downward from left to right, suggesting that as one variable increases, the other tends to decrease. The absence of a clear trend in a no-correlation plot contrasts with the consistent directional relationship observed in a negative correlation plot.
you graph the points going downwards
No, you draw a general line through the middle of the points.(A line of fit)
Scatter Plot.
A scatter plot shows a correlation when there is a discernible pattern in the distribution of data points, indicating a relationship between the two variables. If the points trend upward from left to right, it suggests a positive correlation, while a downward trend indicates a negative correlation. The strength of the correlation can be assessed by how closely the points cluster around a line or curve. If there is no apparent pattern, the variables are likely not correlated.
A straight line which best describes the data on a scatter plot is called a "line of best fit". The line could pass through some of the points, all of them, or none of them.
