Which nine , if it is the first one the answer is
-490,000,000
If it is the second nine the answer is
-489,334,210
It's incorrect. There are 6 moles of NaBr produced for every 3 moles of Na₂S among the reactants (as well as 2 moles of FeBr₃), so the mole ratio of NaBr to Na₂S should be 2 : 1, not 1 : 1.
I think it's the second equation. I could be wrong but I think that's what it is
Y= 5x-45
On your graph go by 5's
On the y go down 9 which going by 5 makes it -45
Then go up 5 and one to the right and plot points keep going. 25/5=5
