Question

What is the graph of the system?
y ≤ -x – 1
y ≥ 2x + 4

Answer 1

This is quite a big assignment eh?

Answer 2

ive already tried doing this somehow i got this wrong

Answer 3

am I correct reading it as y less than or equal to -x -1 AND y greater than or equal to 2x+4

Answer 4

these are the questions i got wrong i missed 9 out of 20

Answer 5

> less than <greater than

Answer 6

always read thes symbols from left to right .
< means that the left is smaller than the right

Answer 7

now im confused

Answer 8

For example 3 < 4 is read as 3 is less than 4.

Answer 9

so im wrong, ehhhhh im lost

Answer 10

which bit is scaring you most?

Answer 11

the part where ive had my signs backwards now im lost

Answer 12

so i have the points graphed just dont know what to shade in lol

Answer 13

This may help you or it may give you an idea. I googled "Graphing inequalities"
http://www.purplemath.com/modules/ineqgrph.htm
Dont give up

Answer 14

Also: http://www.khanacademy.org/math/algebra/linear-equations-and-inequalitie/v/graphing-linear-inequalities-in-two-variables-2

And, as @1on1 said, don't give up...

Answer 15

I always graph the line and the after i look at my graph i choos a point.
BTW do you colour in the region that makes the inequality true?

Answer 16

hahahahah your probly going to say wow this chick is stupid but those pages didnt help me at all

Answer 17

honestly my brain is still stuck on 3rd grade math lol

Answer 18

No I did not know you were a chick !

Answer 19

Some pages don't give instant answers and Khan academy suff is excellent if you give it time.

Answer 20

wow the time limit is almost up and i have 6 more questions to answer if i dont answer them by the end of the time limit then it automatically subbmits its self and i fail again

Answer 21

Answer 23

no i only get to tries

Answer 24

2

Answer 25

That makes it tough!

Answer 26

yep and ive already failed it once

Answer 27

The first one is for y<= -x-1 and the second is for y>=2x+4

How to sketch:

1. Sketch the the line (eg. y<= -x-1 becomes y=-x-1)
2. if it is less than (<) then shade in on the left side. If it is greater than (>) shade in on the right side
3. if it greater than/less than, then you don't darken the line, if it is equal to and less than equal to, then darken the line
