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.

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!
