Algebra 2 Help!

Which equation does the graph of the systems of equations solve?

(Attaching graph) (:

Answer 1

Hm I"m not sure how to solve this problem. But I know a cheat if you're interested

Answer 2

You plug in 2 for each equation, and see which one is equal to -3. Only one of them will be equal to -3 because the two equations only intersect on one point.

Answer 3

I'm sorry you plug 2 into each equation and see which one is correct

Answer 4

@Hero Think you might be able to help?

Answer 5

lazy approach, plug in the x coordinate of the solution into each of the options.

Answer 6

Okay, I'll try it

Answer 7

^What he said

Answer 8

would it be B?

Answer 9

@AdrianK, the proper thing to do would be to show your work. Simply stating what you think to be the answer is the equivalent of guessing. It is preferred that you show or demonstrate WHY you think the answer is B.

Answer 10

I plugged the x coordinate just like you guys said. I did it for each option.
I honestly don't know exactly what I am looking for

This is what I did:

1/2 (2) + 4 = 2(2) - 1

Answer 11

I ended up with 5 = 3

Answer 12

According to the graph, you have two lines that intersect at a point (x,y). The x-coordinate of that point should be inserted into the equation and the result you get should be the
y = y

Both sides of an equation must be equal in order for it to be true.

Answer 13

It's option D! I miss calculated D the first time I did it! I ended up with -3 = -3

Answer 14

Yes, it's D.

Answer 15

Thanks guys!
