Question

What is the system of equations that describes the following graph? Linear Inequalitites
Answers:
x + y < 3
x – y > -2
y ≤ 0

x + y < 3
x – y > -2
x ≥ 0

x + y < 3
x – y > -2
y ≥ 0

x + y > 3
x – y < -2
x ≥ 0

Answer 1

whats the lowest value of x?
and what is the lowest value of y?

Answer 2

or highest value of y u see there

Answer 3

you dont need the lowest value of x or y....to solve

Answer 4

lets just write equations of those 2 lines

Answer 5

ok!

Answer 6

it is A.

Answer 7

no its not A lol

Answer 8

if you serperately graph each function, and shade in the overlapping, then it should be it

Answer 9

it is A.....

Answer 10

uhh no lol first notice that the horizotal like is x>= 0

Answer 11

line*

Answer 12

oh wait
no
b

Answer 13

i was solving it and i didnt see the x and y >.>

Answer 14

yeah its b.. derp lol

Answer 15

ok good >< now let me explain it for this guy

Answer 16

its good to explain all the basics and fundamentals!

Answer 17

hahaha all good :)

Answer 18

okay lets write equations of these lines that we are working with!

Answer 19

you already saw, that the horizontal line was x=0
basically for all value of y, x =0 at that point

Answer 20

ok

Answer 21

what about the other 2 lines, can u tell me the equation of the line with the positive slope

Answer 22

I can't im just writing everything down as you tell me. Im the worst at graphs

Answer 23

have you learnt about equation of a line yet

Answer 24

ok

Answer 25

what is the slope of the line on that graph?

Answer 26

for your diagram

Answer 27

slope is = the rise/run

Answer 28

or the change in Y/ change in X

Answer 29

Ummm....-3

Answer 30

how did u get that

Answer 31

I looked at the lines on the diagram

Answer 32

tell me 2 points on that line
and ill show u how to get the slope

Answer 33

take any 2 easy to read points on that line

Answer 34

-3 and 2

Answer 35

what is that
these are points
a point has an x value and y value to it
because it is location on a 2 axis grid
