Let's break down the expression \(9x + 4y - 5\):
-
This expression has 3 terms. (The terms are \(9x\), \(4y\), and \(-5\).)
-
The coefficient of \(x\) is 9. (The coefficient is the number in front of the variable \(x\).)
-
The coefficient of \(y\) is 4. (The coefficient is the number in front of the variable \(y\).)
-
The constant in this expression is -5. (The constant term is the number without a variable, in this case, \(-5\).)
So, filling in the blanks:
- This expression has 3 terms.
- The coefficient of \(x\) is 9.
- The coefficient of \(y\) is 4.
- The constant in this expression is -5.
