Solve the equation $9 x - 7 y = 11$ for $y$ .
A) $y = \frac { 11 - 9 x } { 7 }$ or $y = 1.57 - 1.29 x$

B) $y = \frac { 11 + 9 x } { 7 }$ or $y = 1.57 + 1.29 x$

C) $y = \frac { 9 x - 11 } { 7 }$ or $y = 1.29 x - 1.57$

D) None of the above.

To get $y$ by itself, we need to isolate it on one side of the equation. We can begin by subtracting 9x from both sides of the equation to get:
$$-7y = 11 - 9x$$
Then, we can divide both sides by -7 to get:
$$y = \frac{11 - 9x}{-7} = \frac{9x - 11}{7}$$
So, the correct answer is C. The other answer choices are incorrect, possibly due to errors in calculation.
