Ineed someone to tell me if my parallel line equation is correct and to tell me what the perpendicular line equation is. you!

The parallel equation is correct

to calculate the perpendicular line you know m=9 of your given line

for two perpendicular lines the following is always true:
m₁*m₂=-1
insert your m:
9*m₂=-1
m₂=-1/9

so y=(-1/9)x+b is some perpendicular line

insert the point (2,-3):
-3=(-2/9)+b
(-27/9)-(-2/9)=b
(-27/9)+(2/9)=b
(-25/9)=b

so y=(-1/9)x-(25/9) is perpendicular and passes the given point
