 The COEFFICIENT tells youhow many of the variable youhave.  It is ALWAYS the numbernext to the variable. The Constant is the number that doesn'tchange - it is not next to a variable - it isall by itself. The variable is the letter used to represent anunknown value, like x or y or a or b. Let's practice....Find the coefficient...3x + 12 Let's practice....Find the coefficient...7x - 5 Let's practice....Find the coefficient...-2x + 10 Let's practice....Find the coefficient...7+12x Let's practice....Find the constant...it is the number by itself7+12x Let's practice....Find the constant...it is the number by itself6 - 3x Let's practice....Find the constant...it is the number by itselfRemember, if it says -8, that is the same as+ (-8).  Watch your sign here!4x - 8 Let's practice....Find the variable...it is the letter that representsthe unknown value.4x - 8 Let's practice....Find the variable...4 - 2a Let's practice....Find the variable...13y + 4
