Answer:

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 : 
Answer:

Step-by-step explanation:
You factor out the common term first.
You should get the equation below.

then you get rid of the negative inside
and will be simplified to this.
