Y - y1 = m(x - x1)
slope(m) = -4/3
(0,-12)....x1 = 0 and y1 = -12
sub
y - (-12) = -4/3(x - 0) =
y + 12 = -4/3(x - 0) <=== point slope form
y + 12 = -4/3x
y = -4/3x - 12 <=== slope intercept form
y = -4/3x - 12
4/3x + y = -12
4x + 3y = -36 <=== standard form
Well you see, you have 2/8, (fraction) and here is a few others,
These are COMMON. 4/16, 2/8, 6/24, etc....
You multiply the denominator and numerator by the same answer.
Thats how I think I learned it.
