Answer:
D. 
Step-by-step explanation:
The point-slope form of a line is given by:

The line given to us has equation;
.
The slope of this line is -4. The of the line perpendicular to this line is the negative reciprocal of the slope of the given line.
Our slope of interest is therefore; 
Since the point goes through (-2,7), we have
.
We plug in the slope and the point into the point-slope formula to obain;

The required equation is:

Step-by-step explanation:
There will be 2 squares. Those can be 9. Those are:
One square can be a 3 by 3 square, meaning each side will be 3 units. The area for this will be 9.
Another one is the square can be a 9 by 9 square, meaning each side will be 9 units. The area for this will bebe 81.
