Answer
(b).
Work Step by Step
The equation of a least-squares regression line: $\hat{y}=a+bx$, where $x$ is the appraised value and $y$ is the price.
We can find the $y$-intercept $a$ in the row "Constant" and the column "Coeff", thus $a=111.9$.
We can find the slope $b$ in the row "appraised" and the column "Coeff," thus $b=1.2103$.
Thus the equation becomes: $price=111.9+1.2103x$, thus the answer is (b).
