Ab and bc form a right angle at point b if a = (-3,-1) and b = (4,4) what is the equation if bc

Step-by-step explanation:

Refer the attached figure .

We are given a line AB

Point A

Point B

Formula for slope 'm' when two points are given :

Substituting thew values

Since we are given that AB is perpendicular to BC

So, By property - perpendicular slopes are negative reciprocals of each other.

So, Slope for line BC :

Point B = (4,4)

Formula of equation of line :

Hence the equation of line BC :

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4
