Given:
Equation of line is 
.
The perpendicular line passes through (-2,-6).
To find:
The point slope form of perpendicular line.
Solution:
We have,
On comparing this equation with 
, we get
Slope of given line is 
.
Product of slopes of two perpendicular of the lines is -1.
So, 
Slope of required line is -4 and it passes through (-2,-6). So, the point slope form is
where, m is slope.
Therefore, the correct option is A.
Answer:
The answer would be 122.4
because 9 x .6 = 5.4
and 9 x 6.5 = 58.5
and 58.5 x 2 = 117
117+5.4=122.4

An equation is formed of two equal expressions. The original height of the water in the pool in feet is 5.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given the equation, 4.75 = x + (-0.25) can be used to find x, the original height of the water in a pool. Therefore, the height of the fool in the beginning is,
4.75 = x + (-0.25)
4.75 + 0.25 = x
x = 5
Hence, the original height of the water in the pool in feet is 5.
