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

  • Math Help PLEASE - ,

    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
