Blue part:
The blue dashed line passes through the points:
P1=(-1,0)=(x1,y1)→x1=-1, y1=0
P2=(0,2)=(x2,y2)→x2=0, y2=2
We can find the equation of this line using the Point-slope equation:
y-y1=m(x-x1)
m=(y2-y1)/(x2-x1)
m=(2-0)/(0-(-1))
m=(2)/(0+1)
m=(2)/(1)
m=2
y-0=2(x-(-1))
y=2(x+1)
y=2x+2
The inequality for the blue area is:
y<2x+2 

Yellow part:
The line passes through the points:
P1=(0,-1)=(x1,y1)→x1=0, y1=-1
P2=(1,1)=(x2,y2)→x2=1, y2=1
We can find the equation of this line using the Point-slope equation:
y-y1=m(x-x1)
m=(y2-y1)/(x2-x1)
m=(1-(-1))/(1-0)
m=(1+1)/(1)
m=(2)/(1)
m=2
y-(-1)=2(x-0)
y+1=2x
y=2x-1
The inequality for the yellow area is:
y>=2x-1

The system of inequalities is:
 (1) y<2x+2
(2) y>=2x-1

A point solution to the system is the Origin O=(0,0)

For the first part, it is y < 2x + 2
& the second part is (-1, -2)
