ax + by = c - the equation
by = c - ax - get
by
isolated by subtracting
ax
from both sides
y = c/b - (a/b)x - divide by
b
on both sides and get the answer
i think that's how it works

Ax + By = C
Ax + By - C = 0
Ax - C = -By
(C/B) - (Ax/B) = y
Re-written to be in the form your teacher probably wants:
y = -(A/B)x + (C/B)

also it shouldn't matter if its -(Ax/B) or -(A/B)x because doing it either way gets the same answer
