The distance from A to B will be negative when the line is trending downward from left to right.
Answer:
All you need to do is subtract the coefficient.
Step-by-step explanation:
For example a minus b is c. So this is simply going to be c times d to the e you can do that if these two are the same.
Answer:
(-21,-19)

Standard form
Step-by-step explanation:
We are given the equation of circle

General equation of circle:

Centre: (-g,-f)
Radius: 
Compare the equation to find f, g and c from the equation



Centre: (-21,-19)
Radius (r) 
Standard form of circle:

The centre of circle at the point (-21,-19) and its radius is
.
The general form of the equation of a circle that has the same radius as the above circle is standard form.
