If someone could i would really appreciate it!
u can do it

This is point slope form so you start with
y-b = m(x-a)
then you would find a point (5, - 1)
then fill in
y-5 = 3(x-1)
then if you want solve it for slope intercept form
y = 3x + 2 
graph that and check your work

Yes, two vertical lines can be complementary

Think of it as five or above give it a shove. change the 5 or above to the right to a zero and add one to the number on the left.
