5x-3y<15

Answer 1

1.Given : Inequalities and

To find : Solve the system of inequalities by graphing ?

Solution :

Let the equation 1 -

Equation 2 -

Plot these equation in the graphing tool,

Equation 1 is shown by red dotted line.

Equation 2 is shown by blue dotted line.

The intersection point of the equations is the solution of the system i.e. (0,-1).

Refer the attached figure below.

The solution of inequalities is at (0,-1).

2. Y=5-2x/3
