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.

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
