Answer:
Point slope form : 
Slope intercept form: 
Standard form : 
Step-by-step explanation:
From the given graph it is clear that the line is passing through the points, (-4, 0), (-2, 1), (0, 2), and (2, 3).
If a line passes through two points
and
, then the equation of line is

Let as consider any two points of the line: (2, 3) and (0, 2).
The equation of line is


The point slope form of the line is
.


Add 3 on both sides.


Therefore the slope intercept form of the line is
.
Multiply both sides by 2.


Therefore, the standard form of the line is
.
