Can you get me the answers for these two questions I really need help

3. In the linear regression equation of the form y = ax + b, the interpretation of A is: A. The y-intercept which means the initial value of y when x = 0 B. The slope of the line which means the average rate of change of y with respect to x. C. The linear regression coefficient D. The coefficient of determination 4.
