Answer:
Step-by-step explanation:
The axis of symmetry can be calculated using the formula:
First we must determine a and b from the quadratic: 
. This is in standard form, with the highest power first in descending order.
Standard form is also: 
If we compare this to the quadratic given, we can conclude that:
Substitute the values for a and b into the formula.
Multiply in the denominator.
Divide.
This can also be determined from the graph. It is the x-coordinate of the vertex or the maximum/minimum. It divides the quadratic into 2 symmetrical halves.
-1/9+-5/9=
When you are adding a negative number, the operation turns into subtraction:
-1/9-5/9=
Really, it's just subtraction. The simplest form is -2/3, which is equal to -0.66667.
I hope this helps :)
