Rom4ik [11]

Answer:

-2

Step-by-step explanation:

In a linear regression model we have the equation $Y = b_{1}X + b_{0}$ that relates $X$ and $Y$ , where $b_{1}$ is the estimator of the slope and $b_{0}$ is the estimator of the Y-intercept. The coefficients $b_{1}$ and $b_{0}$ can be estimated with the equations:

$b_{1} = \frac{S_{xy}}{{S^{2}}_{x}}$

$b_{0} = MY-b_{1}MX$ . Thus,

$b_{0} = 6 - (4)(2) = -2$
