Lesson 1-1: Systems & Linear Programming

Sorry, the GeoGebra Applet could not be started. Please make sure that Java 1.4.2 (or later) is installed and active in your browser (Click here to install Java now)


The student will be able to solve systems of linear equations and linear programming problems, including setting up a system of constraints, graphing the system, and identifying the optimum values.

Graphical solutions of solving equations

Two straight lines y=mx+c and y=nx+d are displayed.
The x coordinate of the point at which the lines intersect (indicated by the green arrow) will be the solution to the equation: mx+c = nx+d
Move points B and C. When do the fruits change?
How many solutions can such equations have? At most? At least?
