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

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

2. Express your answer in the form y=mx+b.
(-4,8); 8x=7y+9

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

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

    I will do one of them for you

    #2.
    parallel to 8x= 7y + 9 , so the only thing that will change is the constant
    new equation:
    8x = 7y + k
    sub in the point (-4,8)
    -32 = 56 + k ---> k = -88
    new equation : 8x = 7y + 88
    7y = 8x - 88
    y = (8/7)x - 88/7
