Question 426938: A little help please?!
Find the system of inequalities whose feasible region is the interior of the rectangle with vertices (corner points) of (-3, 4); (5, 4); (5, -1); (-3, -1)
I have NO idea??
Thank you in advance!! :)

you need to find the equation of the lines that make up the sides of this rectangle.

from the looks of your points, you have a vertical line that can be created between the points of (-3,4) and (-3,-1). it's a vertical line because the x-value remains the same while the y-value changes.

you have another vertical line that can be created between the points of (5,4) and (5,-1).

you have a horizontal line that can be created between the points of (-3,4) and (5,4). it's a horizontal line because the y-value remains the same while the x-value changes.

you have another horizontal line that can be created between the points of (-3,-1) and (5,-1)

your shaded region will be within the rectangle formed.

let's create the equations of the lines involved.

your 2 vertical lines will have the equations of x = -3, and x = 5.

your 2 horizontal lines will have the equations of y = 4, and y = -1.

your shaded region within the rectangle will be formed from the equations.

x > -3 and x < 5 which can be written as -3 < x < 5.

and:

y > -1 and y < 4 which can be written as -1 < y < 4.

x > -3 would be the area to the right of the line x = 3.
x < 5 would be the area to the left of the line x = 5
y > -1 would be the area above the line y = -1.
y < 4 would be the area below the line y = 4.

the area on the graph that is common to all these requirements is the area within the rectangle formed by the equations of these lines.
