How do I plot following constrains in graph.

1. w + 4 s <= 20
2. 8 <= w <= 26 and
3. 2 <= s <= 5
I could find coordinates for constrain 1 as (3,8) and (2,12)

To plot the given constraints on a graph, you will need to consider the variables w and s separately.

1. Start by graphing the first constraint:
- The equation is w + 4s <= 20.
- To plot this on a graph, you can first convert it into slope-intercept form (y = mx + c): w = -4s + 20.
- Now, choose different values for s (within the given range) and calculate the corresponding values of w using the equation.
- For example, when s = 2, w = -4(2) + 20 = 12. So, one point on the graph is (12, 2).
- Similarly, when s = 5, w = -4(5) + 20 = 0. Another point on the graph is (0, 5).
- Plot these two points and draw a line passing through them. Remember to draw the line as a dashed line since it is an inequality.

2. Now, let's graph the second constraint:
- The given range for w is 8 <= w <= 26.
- This means w can take any value between 8 and 26, including the endpoints.
- On the graph, draw a vertical line from w = 8 to w = 26. This represents the range of values for w.

3. Lastly, graph the third constraint:
- The given range for s is 2 <= s <= 5.
- Similarly, draw a horizontal line from s = 2 to s = 5 on the graph. This represents the range of values for s.

Now, you will have three lines on the graph:
- The line representing the first constraint w + 4s <= 20.
- The vertical line representing the range of values for w.
- The horizontal line representing the range of values for s.

The feasible region, where all the constraints are satisfied simultaneously, will be the area common to all three lines.

It is important to note that the points (3, 8) and (2, 12) mentioned in the question are not the correct coordinates for the first constraint. They seem to be calculated incorrectly based on the equation w + 4s <= 20.
