Answer 1

To identify which of the given expressions has a linear term (the \(x\) term) with a coefficient of \(-1\), let's examine the coefficient of the \(x\) term in each expression:

1. \(-x^2 + 3x + 1\): The coefficient of \(x\) here is \(3\).

2. \(2x^2 + 6x - 1\): The coefficient of \(x\) here is \(6\).

3. \(3x^2 - x - 4\): The coefficient of \(x\) here is \(-1\).

4. \(-2x^2 + x + 7\): The coefficient of \(x\) here is \(1\).

The expression that has a linear term with a coefficient of \(-1\) is:

\(3x^2 - x - 4\).
