Question

Use a graph and a table to solve the system. Check your answer. Enter your answer as the following example: (5, -3).

{3y + 6x = 3
x - y = -7

Answer 1

Here, they want you to graph the two equations given, and see if they reach the point (\(5,-3\)) at all.
I would put both equations in point-slope form, \(y=mx+b\), so it is easier to graph them.
For instance, \(x-y=-7\) becomes \(y=x-(-7)\) or \(y=x+7\).

Answer 2

Let's try \(3y+6x=3\). How would you put that in the form of \(y=mx+b\)?

Answer 3

umm y=-2x+1

Answer 4

right

Answer 5

Yeah. Sorry

Answer 6

So now you have the equations:\[y=x+7\]\[y=-2x+1\]All you need to do now is graph those and then see if they both run into the point (\(5,-3\)) somewhere.

Answer 7

its not looking like it does

Answer 8

Okay, then your answer is No

Answer 9

but thats not what its asking

Answer 10

Oops, I did the first equation wrong.\[x-y=-7\]\[y=-x-7\]

Answer 11

... I'm not exactly sure what they want for "solve the system" sorry

Answer 12

its all good all good you at least helped me with SOMETHING lol

Answer 13

True, true xD
