Step-by-step explanation:
In the given image, the line passes through (-1, -1) and (1, 1).
Let the equation of the line is
, where m is the tangent of the line and c is a constant.
Putting the co-ordinates of the points in the equation, we get
and 
From the two equations we get, c = 0 and m = 1.
Hence, the function is y = x.
