Answer:

Step-by-step explanation:
Let the equation of the line given in the graph is,
y = mx + b
Where 'm' is the slope of the line
And 'b' represents the y-intercept
Since slope of a line passing through two points
and
is modeled by,
m = 
If this line passes through (-3, 3) and (3, -1),
m = 
m = 
= 
And 'b' = 1
Equation of this line will be,
