To find the coordinates of a feasible region on a Cartesian plane, you first need to identify the constraints that define the region. These constraints are typically represented as inequalities in the form of linear equations.
Once you have identified the constraints, you can plot them on the Cartesian plane to see where they intersect and form the feasible region. The feasible region is the area on the plane where all the constraints are satisfied simultaneously.
The coordinates of the feasible region can then be determined by finding the vertices or corner points of the region. These are the points where the constraints intersect and form the boundaries of the feasible region.
To find the coordinates of the vertices, you can solve the system of equations formed by the constraints at each intersection point. This will give you the x and y coordinates of each vertex, which define the boundaries of the feasible region.

Steps to Find Coordinates of a Feasible Region on a Cartesian Plane:
1. Plot the constraints: Plot the inequalities that define the feasible region in the coordinate plane. For example, if you have the inequality x + y ≤ 5, plot the line x + y = 5.
2. Test a point: Choose a point that is not on any of the boundary lines. If the point satisfies all the inequalities, it is inside the feasible region. If it does not satisfy any of the inequalities, it is outside the feasible region.
3. Shade the feasible region: Shade the region that satisfies all the inequalities. This is the feasible region.
4. Find vertices: The vertices of the feasible region are the points where the boundary lines intersect.
5. Write the coordinates: The coordinates of the vertices can be determined by solving the system of equations formed by the boundary lines.
Example:
Consider the following system of inequalities:
- x + y ≤ 5
- x ≥ 0
- y ≥ 0
Steps:
1. Plot the constraints:
- Plot the line x + y = 5.
- Plot the line x = 0 (y-axis).
- Plot the line y = 0 (x-axis).
2. Test a point: Test the point (2, 3). It satisfies all the inequalities, so it is inside the feasible region.
3. Shade the feasible region: Shade the region below the line x + y = 5 and to the right of the lines x = 0 and y = 0.
4. Find vertices: The vertices are:
- (0, 0)
- (5, 0)
- (0, 5)
5. Write the coordinates:
- Vertex 1: (0, 0)
- Vertex 2: (5, 0)
- Vertex 3: (0, 5)
