Question

can someone please help me fix my math problem? please? I will fan and give a medal!!
Question~ graph the following inequalities.
x + y => -4
My steps~Steps ~
Replace the inequality sign with an = sign and graph the line.
x + y > -4
Graph the intercepts: (-4, 0) & (0, -5), and draw the line.
Using the original inequality, check the inequality sign.
x + y > -4 means a Sold line.
Pick a point on either side of the line.
Choose (0, 0) since it is NOT on the line. Substitute into
x + y > -4
(0)+(0)> -4
0> -4 This is true

Answer 1

what my teacher said was wrong~
Did you hit the wrong key here: Graph the intercepts: (-5, 0) & (0, -4)

Answer 2

@mathwizzard3 could you try to help me?

Answer 3

Do you think you could ask your teacher?

Answer 4

Where did you get (-4, 0) & (0, -5) from?

Answer 5

those are the points that I graphed

Answer 6

Okay, why don't we just work this out together and see what happens

Answer 7

Wait no let me just explain to make it faster

Answer 8

XD sorry

Answer 9

Lets plug in these two points you decided on!

Answer 10

So we will plug in the x coordinate for x and the y coordinate for y \[-4 + 0\ge-4\]

Answer 11

It would be true because 0 + -4 = -4 so -4=-4 so that much is correct

Answer 12

Now lets plug in the next points\[0 + -5\ge-4\]

Answer 13

Lets see if this is correct. Is -5 equal to -4?

Answer 14

@abbycross167

Answer 15

no sir/ma'am

Answer 16

sir :P

Answer 17

Alright, is -5 > -4

Answer 18

no sir

Answer 19

That is where you messed up, those points (0, -5). I suppose you should change those to something like (0, -3).

Answer 20

Do you understand?

Answer 21

so I just have to change -5 to -3?

Answer 22

Something like that it just has to be plugged into the equation and be true.

Answer 23

oh okay, is that all?

Answer 24

I haven't read it all, did your teacher say there was anything else wrong?

********Where I put the other stars make sure you say it is a \[\ge \] sign not a > sign. Other than that I think it is all good!

Answer 26

I put that in the wrong order but say it is equal to or greater then not just greater than :)

Answer 27

I would appreciate a medal :P It's fine if you don't give me one

Answer 28

I have a question... all of the > signs in the steps would all of them be =>?

Answer 29

I'm so sorry....but yes they would :)
