Answer:
The required equation is y+2=-(x-4), therefore the correct option is 3.
Explanation:
From the graph it is clear that the line is passing through the points (4,-2) and (0,2).
The slope of the line is

The slope of the line is -1.
The point slope form of a line is



The required equation is y+2=-(x-4), therefore the correct option is 3.
