m = (y2 – y1) / (x2 – x1)
m = –3 – 6 / 2 – (–1)
m = –9 / 3
m = –3
y – y1 = m (x – x1).
y – 6 = –3 (x + 1)
y – 6 = –3x – 3
y – 6 + 3x + 3 = 0
y + 3x – 3 = 0
3x + y – 3 = 0
x * (–6) * 1 = 6x
y * 1 * 2 = 2y
1 * (–1) * (–3) = 3
1* 6 * 2 = 12
x * 1 * (–3) = –3x
y * (–1) * 1 = –y
s: 6x + 2y + 3 – (12 – 3x – y) = 0
s: 6x + 2y + 3 – 12 + 3x + y = 0
