The equation 3x-2y=6 is an example of which type of equation?

  1. Quadratic

  2. Exponential

  3. Linear

  4. Radical

The correct answer is: Linear

This equation is considered a linear equation because the variables are raised to the first power and there are no constants multiplied together. A quadratic equation has variables raised to the second power and an exponential equations has a variable as the base of an exponent. A radical equation has a variable under a radical symbol, which is not the case in the given equation. Therefore, only linear is the correct classification for this equation.
