The standard form of a linear equation is Ax + By = C where A and B are not both zero and A, B and C are integers whose GCF is 1.
To convert the equation y = 9x - 1 to standard form, we need to rearrange it as:
9x - y = 1
We can divide both sides by -1 to get
-9x + y = -1
Which is the standard form of the equation.
So the standard form of the equation is:
-9x + y = -1
