(8,-1);
5x-9y=7
-9y=-5x+7
y=-5x/-9+7/-9
y=5x/9-7/9 this line has a slope=5/9.(red line)
Parallel lines will also have a slope=5/9.
-1=5/9*8+b
-1=40/9+b
b=-1-40/9
b=(-1*9-40)/9
b=(-9-40)/9
b=-49/9
y=5x/9-40/9 (green line)
(graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions 5x/9 -7/9 and 5x/9 -40/9
