Which function is graphed below?

Answer:
Hence, the correct option is A.
Step-by-step explanation:
As given by the question
There are given that the graph of the line.
Now,
To find the equation of the line, first, choose the two intersect point
So,
The intersection point is:
(0,1) and (1,0)
Now,
From the formula of slope:
[tex]m=\frac{y^{2}-y^{1} }{x^{2}-x^{1} } [/tex]
Then,
From the two-point form formula:
y-y^1=m(x-x1)
