Question 1028297: I don't understand these types of problems? Please help!
Graph each system of inequalities. Name the coordinates of the vertices of the feasible region. Find the maximum and minimum values of the given function.
1. 5 ≥ y ≥ -3
4x + y ≤ 5
-2x + y ≤ 5
f(x, y) = 4x - 3y
2. x ≥ -10
1 ≥ y ≥ -6
3x + 4y ≤ -8
2y ≥ x - 10
f(x, y) = 2x + y

--------------
1. 5 >= y >= -3
Enter F6, then 5 >= y >= -3
================================
The rest are similar.
-------
4x + y ≤ 5
-2x + y ≤ 5
f(x, y) = 4x - 3y
2. x ≥ -10
1 ≥ y ≥ -6
3x + 4y ≤ -8
2y ≥ x - 10
f(x, y) = 2x + y
