The reason is that the straight line equation is used to illustrate the relation between the rate of return and the beta factor and is given as under:
Y = a + bX
Here
a = Rf
B = Risk premium = Rm - Rf
X = Beta Factor
So this means the security market line is the graphical presentation of capital asset pricing model and illustrates why the increase in beta factor increases the required rate of return, the reason is that the the overall required return Y of the investment will start increasing with the increase in the beta factor.
