A market's return is $R_M = 0.1$ and its standard deviation is $0.175$.The risk free rate of return is $r_f = 0.03$.
A portfolio $P$ has an expected return of $0.13$ and an expected $\beta$ value of $1.8$.
How do I deduce whether or not this portfolio lies on the Capital Market Line?
I know that the equation of the SML is given by $$R_P = r_f + \frac{R_M - r_f}{\sigma_M} \times \sigma_{P}$$
Do I just check if both sides of this equation are equal? If so, how would I deduce the standard deviation of the portfolio?
