Answer:

Step-by-step explanation:
Co-ordinates of point A = ( -7 , 1 )
Co-ordinates of point M = ( -2 , 2 )
Let the co-ordinates of point B be ( x , y )
A ( -7 , 1 )
( x1 , y1 )
B ( x , y )
( x2 , y2 )
Now,
Midpoint = 
⇒
Finding the value of x :

The equation of the line is 
Explanation:
The equation of the line is perpendicular to
The equation is of the form
where m=-14
<u>Slope:</u>
The slope of the perpendicular line can be determined using the formula,



Thus, the slope of the line is 
<u>Equation of the line:</u>
The equation of the line can be determined using the formula,

Substituting the slope
and the point (2,-4), we get,

Simplifying, we get,



Thus, the equation of the line is 
Answer:
51,000,000,000
Step-by-step explanation:
the 10^8 usually determines how many 0's will be added to the right side of the number
thus- 510x10^8 = 51,000,000,000
