Question

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

Answer 1

it's d

Answer 2

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.

Answer 3

And I dont have to use the midpoint formula?

Answer 4

Not at all.

Answer 5

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

Answer 6

D is right

Answer 7

Answer 9

thank you guys!

Answer 10

You're welcome

Answer 11

:)

Answer 12

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 :)

Answer 13

:) Thanks!

Answer 14

anytime
