term, or linear term, have a coefficient of −1
?(1 point)

−2x2+x+7

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:

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