(x₁,y₁) = (2,-3)
(x₂,y₂) = (2,9)
To determine the slope using two points lie on the line, we could use the following formula
m =
plug in the numbers
m =
m =
m =
m = undefined
The slope is undefined, the line is vertical

Given:
The graph of the system of inequalities.
To find:
The system of inequalities.
Solution:
From the given graph it is clear that the first line passes through the points (0,2) and (1,-1). So, the equation of the boundary line is:
The shaded region lies above the line and the boundary line is a solid line. So, the sign of inequality must by ≥.
The second line passes through the points (0,-2) and (3,0). So, the equation of the boundary line is:
The shaded region lies above the line and the boundary line is a solid line. So, the sign of inequality must by ≥.
Therefore, the system of inequalities contains two linear inequalities and
