Answer:
-4/5
Step-by-step explanation:
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:

Answer: Given as,X=2 & Y=3,
now multiplying we get,
2xxy=2×2×3=12
Ans.) 12
