Answer:

Step-by-step explanation:
To write the equation of a circle, use the formula
where the center of the circle is (h, k).
This means the equation is
.
Find the radius r by dividing the diameter of 10 in 2. The radius is 5.
So the equation of the circle is 
If x = 8, then the factor is (x - 8); likewise, if x = -5, then the factor is (x + 5). FOIL those together and get B
Answer:

Step-by-step explanation:
If A = (-3,-1) and B = (4,4), the slope of AB is

Two perpendicular lines have slopes that have product of -1:

The equation of the line BC with slope -1.4 and passing through the point B(4,4) is
