Solve the following inequalities graphically in two dimensional plane: 3y−5x<30
Consider: 3y−5x=30
x0−63y10015
Putting (0,0) in the given inequation, we have −3×0−5×0<30
⇒0<30, which is true.
∴ Half plane of 3y−5x<30 is towards origin.
Solve the given inequality graphically in two-dimensional plane: 3y – 5x < 30
