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
