Lesson - Constant Coefficient and Variable

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. 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 itself 7+12x Let's practice.... Find the constant... it is the number by itself 6 - 3x Let's practice.... Find the constant... it is the number by itself Remember, 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 represents the unknown value. 4x - 8 Let's practice.... Find the variable... 4 - 2a Let's practice.... Find the variable... 13y + 4 |
