1. if the risk-free return were 4.0% and a security's beta coefficient were 2.0, what would be the required rate of return for the security? 4% 5% 10% 14% 2. if the risk-free return (inflation) increases by 2 percentage points, the required rate of return stays the same for all securities increases the same 2 percentage points for all securities increases for some securities and decreases for others depending on the beta coefficient cannot be determined without more information 3. if the risk-free return (inflation) increases by 2 percentage points, then for the security market line both the y-intercept and the slope remain the same the y-intercept changes and the slope remains the same the y-intercept remains the same and the slope changes both the y-intercept and the slope change
