Question

Solve the system of equations by graphing
9x-7y=-49
9x=7y-49

Answer 1

they are the same equation

Answer 2

Do I need to change it to y=mx+b

Answer 3

y=7+(9/7)x

Answer 4

no
look at the first equation, visualize adding \(7y\) to both sides and see that you get the second equation exactly

Answer 5

i dont think you wrote the problem correctly because they are the same equation
yes because thats the way you know how to graph it

Answer 6

It is written correctly. I am so confused.

Answer 7

look at the first equation
it says
\(9x-7y=-49\)
now you can rearrange this equation any way you like, and it will still be the same equation
for example you can write it as
\(7x-7y+49=0\) by adding 49 to both sides. it is still the same equation, it just looks different

Answer 8

you can also write it as
\[9x=4y-49\] by adding \(4y\) to both sides. nothing has changed
that is why i said the first equation is the same as the second one

Answer 9

ok so then i dive 9 by both?
