Concept:
Correlation refers to the relationship between two variables. It is a statistical technique used to measure the extent to which two variables are related to each other. Correlation can be positive, negative or zero.
Solution:
Given, y = 4x + 3
To find the correlation between x and y, we need to plot the values of x and y on a scatter plot.
Plotting the values of x and y, we get the following scatter plot:
Scatter Plot:
From the scatter plot, we observe that the points lie on a straight line passing through the origin with a positive slope. This indicates that as the value of x increases, the value of y also increases.
Hence, we can conclude that the correlation between x and y is positive.
Therefore, option (C) is the correct answer.
