How do you put this in standard form with the y=mx+b method?

we have
point (3,5)
m=5/3
step 1
Put in slope intercept form
y=mx+b
substitute the given values
5=(5/3)(3)+b
solve for b
5=5+b
b=0
therefore
y=(5/3)x
step 2
Put in standard form
Ax+By=C
where
A is a postive integer
B and C are integers
so
y=(5/3)x
Multiply by 3 both sides
3y=5x
