Step-by-step explanation:
let eqn be y = mx + b.
2x + 9y = 8
9y = -2x + 8
y = -2/9 x + 8/9
since the lines are perpendicular, product of the slope of the two lines = -1.
hence,
m x -2/9 = -1
m = 9/2
sub (0, -3):
-3 = 9/2(0) + b
b = -3
therefore equation is: y = 9/2x - 3

Answer:
8/10, 16/20 and more!!
Step-by-step explanation:
if you multiply both the top number by 2,
you will get 8/10!! this is the same amount
just dividing each fifth into smaller pieces
you can go further and do 16/20, 32/40
64/80, 128/160 and INFINITE WAYS MORE!!
