To find the coefficient and exponent of the expression \(-2a\), let's break it down step by step:
1. Identify the coefficient:
The coefficient is the numerical factor that is multiplied by the variable. In the expression \(-2a\), the numerical factor is \(-2\). Therefore, the coefficient is \(-2\).
2. Identify the exponent:
The exponent is the power to which the variable is raised. In the expression \(-2a\), the variable \(a\) is raised to the power of 1. This is because \(a\) can be written as \(a^1\), even though the exponent is not explicitly shown. Therefore, the exponent is 1.
Given these findings:
- The exponent is 1.
- The coefficient is \(-2\).
So the correct answer is:
The exponent is 1 and the coefficient is -2.
