Have been spelled out case-by-case by the supreme court.
The answer is 2003
because i researched the to make sure the answer was right
Parallel lines has the same slope, hence the slope of the line in question is -2 (y = mx + c)
(y - y1)/(x - x1) = m or y - y1 = m(x - x1)
y - 7 = -2(x - 1)
y - 7 = -2x + 2
y = -2x + 9
