Option C is correct. For a simple linear regression model, the slope term is the change in the mean value of y associated with a one-unit increase in x.
For a simple linear regression model, the required formula for expressing the model is y = mx + b where:
m is the slope
b is the y intercept
Slope "m" is also known as the rate of change in y with respect to a unit change in x.
Hence according to the given question, for a simple linear regression model, the slope term is the change in the mean value of y associated with a one-unit increase in x.
