If the correlation coefficient is 0, the two regression lines are perpendicular.

This is because a correlation coefficient of 0 indicates no linear relationship between the variables.

This causing the regression lines to be at right angles to each other.

Explanation

To form a differential equation from a given function containing arbitrary constants:

• If the function has 'n' arbitrary constants, differentiate the equation 'n' times with respect to the independent variable.
• This process removes the arbitrary constants, leaving a differential equation.

If there is exactly one solution, the system is independent.

If there are infinitely many solutions, the system is dependent.
