## Nana3456 3 years ago PleaSE help me!! Which of the below systems of equations matches the following graph? (graph attached below) x – 3y = 9 2x + 3y = 0 x + 3y = –9 2x + 3y = 0 x – 3y = –9 2x – 3y = 0 x + 3y = 9 2x – 3y = 0

it's d

Just isolate the y on one side to get a y=mx+b equation wiht m being the slope and b being the y-intercept. It's easier to tell the shape of a graph this way.

4. Nana3456

And I dont have to use the midpoint formula?

5. j814wong

Not at all.

6. Nana3456

oh I was confused I thought I had to use both..

7. Nana3456

D is right

8. j814wong

Yeah. As Ghazi said. I just helped you figure out the answer yourself to understand the question.

You're welcome

you should have checked a one pair of point for single line and in just two steps you might have got your answer..by the way you're done now :)
