Enter the slope and the coefficient of “a” into the Calculator. The calculator will evaluate the Axis of Symmetry Equation.

## Axis of Symmetry Equation Formula

x = -b/2a

Variables:

- x is the Axis of Symmetry Equation ()
- b is the slope
- a is the coefficient of a

To calculate Axis of Symmetry Equation, divide the negative value of the slope by 2 times the coefficient of a.

## How to Calculate Axis of Symmetry Equation?

The following steps outline how to calculate the Axis of Symmetry Equation.

- First, determine the slope.
- Next, determine the coefficient of a.
- Next, gather the formula from above = x = -b/2a.
- Finally, calculate the Axis of Symmetry Equation.
- After inserting the variables and calculating the result, check your answer with the calculator above.
