Solve the following inequalities graphically in two dimensional plane:
y+8≥2x
The given inequality is y+8≥2x i.e. 2x−y≤8.
Draw the graph of the line 2x-y =8.
Table of value satisfying the equation
2x -y =8
x56y24
Putting (0,0) in the given inequation, we have 2×0−0≤8⇒0≤8, which is true.
∴ Half plane of 2x−y≤8 is towards origin.
