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

#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
