Select the correct answer. and form a right angle at point B. If A = (-3, -1) and B = (4, 4), what is the equation of ? A. x + 3y = 16 B. 2x + y = 12 C. -7x − 5y = -48 D. 7x − 5y = 48

Option C -    

Step-by-step explanation:

Given : AB and BC form a right angle at point B. If A = (-3, -1) and B = (4, 4).

To find : What is the equation of BC ?

Solution :

AB and BC form a right angle at point B.

A=(-3,-1)  and  B=(4,4)

The slope of line AB is

The slope of line AB is

Since the BC is perpendicular to the AB line,

Then the slope of BC is

The equation of line which passes through the point and slope is m is  

Therefore, option C is correct.

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.

i'm sorry mate, but i am not seeing any figures. i am unable to solve this for you.
