3. Vocabulary Linear Equation in 3 Variables:
An equation of the form ax + by +cz = d
x, y, & z are the variables
a, b, c, & d are any real numbers
System of 3 Linear Equations:
3 linear equations each in 3 variables see example 1
Ordered Triple:
Looks like: (x, y, z)
Coordinate in a three dimensional coordinate plane
Solution of a system of 3 Linear Equations:
The solution is an ordered triple that make all three equations in the system true.
