The constant is 3.

This is because when x=1, y=3 and when x=2, y=6 so that is a constant change over each interval as seen in the graph which is 3 :)

Which describes the correlation shown?
VladimirAG [237]
<h2>Answer:</h2>

The correlation that is shown in the scatter plot is:

         Strong positive.

<h2>Step-by-step explanation:</h2>

From the scatter plot we see that with the increase of one variable the second variable also increases.

Hence, the association is positive.

Also, if we draw a trend line that best represents the scatter plot then not all the points will lie above the line but all the data points are either over the line or very close to the line this means that the correlation coefficient is close to 1 but not exactly equal to 1.

            Hence, the correlation is:

               Strong positive.

( For perfect positive all the data points should lie above that line i.e. correlation coefficient must be equal to 1)
