Question 93160: 1) Describe the three possible relationships for two straight lines in the same plane.
2) What is the solution to a system of two equations represented by two parallel lines in the same plane?
3) Describe the steps needed to determine the graph for the solutions to a linear inequality in two variables. What points in the coordinate plane (shaded area) will be selected and why?
4) In a Linear Programming problem you need to maximize a function that contains two variables (such as a and b). Explain what is meant by the constraints for this problem.

1) Describe the three possible relationships for two straight lines in the same plane.
One: intersect at one point; Two: two lines coincide; Three: parallel lines
-----------------------
2) What is the solution to a system of two equations represented by two parallel lines in the same plane?
There is no solution.
-----------------------------
3) Describe the steps needed to determine the graph for the solutions to a linear inequality in two variables.
Graph the boundary lines which are the equality equations associated with
the inequality statements.
-------------
What points in the coordinate plane (shaded area) will be selected and why?
Select a test point; test it in the inequality; if it satisfies the inequality
the half-plane containging the test point should be shaded; it is the solution
set for the inequality.
--------------------
4) In a Linear Programming problem you need to maximize a function that contains two variables (such as a and b). Explain what is meant by the constraints for this problem.
The constraints are the intersection of the solution sets of the various
inequalities.
