Write the equation of the line containing the given point and parallel to the given line.
The equation of the line is y=

Express your answer in the form y=mx+b.
(7,8); x+7y=6

Express your answer in the form y=mx+b.
(8,9); 5x+y=9

Express your answer in the form y=mx+b.
(2,-6); 8x+7y=5

    You do them all the same way. I will only do one.

    7 y = -x + 6
    y = (-1/7) x + 6/7

    slope = m = -1/7
    parallel line is of form
    y = (-1/7) x + b
    solve for b with given point on line
    8 = (-1/7)7 + b
    8 = -1 + b
    b = 9
    so
    y = (-1/7) x + 9
