Answer 1

The correct option is C :

`y = \begin{cases}- 2x + 1& x > 1 \\- x + 2&x\leqslant1\end{cases}`

Explanation:

from the figure

(2,-3) (1,-1) => y = -2x + 1 (x > 1)

(0,2) (1,1) => y = -x + 2 (x ≤ 1)

`(x_1,y_1) \: (x_2,y_2) = >y = (y_2 - y_1)/(x_2 - x_1) \: x + a \\ a = y_1 - (y_2 - y_1)/(x_2 - x_1) \: x_1`
