If the points are called (x1,y1) and (x2,y2)
then the formula is
(y - y2) / (x - x2) = (y1 - y2 / (x1 - x2)
----------------------------------
%28y+-+%28-6%29%29+%2F+%28x+-+0%29+=+%280+-+%28-6%29%29+%2F+%284+-+0%29
%28y+%2B+6%29+%2F+x+=+6%2F4
%28y+%2B+6%29+%2F+x+=+3%2F2
multiply both sides by 2x
2%2A%28y+%2B+6%29+=+3x
2y+%2B+12+=+3x
2y+=+3x+-+12
y+=+%283%2F2%29%2Ax+-+6 answer
