What is the coefficient of the equation -2x^2 + 9x - 4?

-4
-2
9
2

The correct answer is: -2

The coefficient of a term is the numerical value that multiplies the variable. In this equation, the coefficient of the first term, -2x^2, is -2. The coefficient of the second term, 9x, is 9. The constant term, -4, does not have a corresponding variable and therefore has a coefficient of 0. Option C is incorrect because it is the coefficient of the second term. Option C is also incorrect because the coefficient can only be a numerical value and not a variable. Option D is incorrect because it does not correspond to any term in the equation.
