I hope this helps. Answer is in the attachments. :-D
Answer:
slope = -4
Step-by-step explanation:
(y - y1)/(x -x1)
= ( 0 -8)/(5-3)
= -4
points are( 6,2),(7,5) and (3,8)
X,y changes into y,-X
x=31/25
3x+4/5=7-2x
Multiply through by 5
5(3x+4/5)=5(7-2x)
15x+4=35-10x
Collecting like terms
15x+10x=35-4
25x=31
