9/8 that’s what I got but you can reduce it
The +3 is the vertical and the +5 tells you horizontal. so this graph moves 3 up and 5 left. But since it only wants vertical that would be the +3
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 :
