SYSTEMS OF EQUATIONS
A system of equations is a collection of equations that use the same variables.
In a system, a variable represents the same quantity in each equation.
Workbook page 76
Suppose the area of a rectangle is 40 square inches and the perimeter of the same rectangle is 28 inches.
Area and perimeter are found using length (L) and width (W).
You can use this information to write a system about the rectangle.
Both equations use the same variables, and both are about the same rectangle.
The brace shows that the equations are part of a system.
The values for L and W that make the first equation true will also make the second equation true.
This system is true when L=10 and W=4.

Solving a system means finding the values of the variables.
One way to solve a system is by graphing the equations..
You can do this with:
A table of values
OR
Using the Slope and y-Intercept

A system with infinite solutions appears to be one line because both lines occupy the same space.
Every point on one line coincides with a point on the other line.
