Write an equation of the line containing the givin point and parallel to the givin line. Express your answer in the form y=mx+b
The equation of the line is y=?
(5,9);8x=7y+5

since the new line is parallel, it will differ only in the constant,
that is,
its equation will be 8x = 7y + c
plug in the point (5,9)
40 = 63 + c
c = 103
so we have
8x = 7y  103 , rearrange
8x + 103 = 7y
(8/7)x + 103/7 = y
