To find the expression where the coefficient of the linear term (the term with \( x \)) is \(-1\), we need to look at the \( x \) term in each expression.
A) \( 3x^2 - x - 4 \)
The coefficient of \( x \) is \(-1\).
B) \( 2x^2 + 6x - 1 \)
The coefficient of \( x \) is \( 6 \).
C) \( -2x^2 + x + 7 \)
The coefficient of \( x \) is \( 1 \).
D) \( -x^2 + 3x + 1 \)
The coefficient of \( x \) is \( 3 \).
The only expression with a linear term coefficient of \(-1\) is:
**A) \( 3x^2 - x - 4 \)**.
