Lesson - Constant Coefficient and Variable
Contribució de: Nativity
The COEFFICIENT tells you
how many of the variable you
have.  It is ALWAYS the number
next to the variable.
The Constant is the number that doesn't
change - it is not next to a variable - it is
all by itself.
The variable is the letter used to represent an
unknown value, like x or y or a or b.
