The question does not specify any requirements. I'll determine the equation of the line shown in the graph
Answer:
y = -x + 2
Explanation:
Straight Line in Intercept Form
The equation of a line with cuts off intercepts a and b respectively from the x and y axes is:

The intercepts of the line shown on the graph are a=2, b=2, thus:

Multiplying by 2 we get the general form of the line:
x + y = 2
The equation in slope-intercept form is:
y = -x + 2
