Question

PLEASE HELP ME

Answer 1

do you know how to graph the lines? just like regular slope intercept form?

Answer 2

once you graph the lines pick a spot on the graph and plug it into the equation then see if it solves it, if it doesn't solve it the shade in the other direction and pick a point from the shaded side and use that as one of the possible solutions

Answer 3

@Ednac i dont know how please help

Answer 4

Ok so lets take the equation: y>2x+2. What information do we have with this?

Answer 5

slop and the y intercept

Answer 6

slope*

Answer 7

so graph the point of the y intercept and apply the slope

Answer 8

can you do that much?

Answer 9

dont i have to shade a side in ? and i'll try

Answer 10

can you check it to see if it is right?

Answer 11

we are getting to the shading, but first you need a line, and yes i can check

Answer 12

ok ty

Answer 13

np

Answer 14

no we have a positive slope here

Answer 15

and its rise over run

Answer 16

so the slope is going up 2 and over 1

Answer 17

up 2 over to the right 1

Answer 18

this is because the slope is positive

Answer 19

that is almost right... Why did you move the y intercept?

Answer 20

its still 2

Answer 21

the y intercept is always (0,y)

Answer 22

perfect

Answer 23

:D

Answer 24

now pick a point on the graph, i like to use (0,0) because it is easy

Answer 25

and plug it into the equation

Answer 26

and tell me if it makes the equation correct or not

Answer 27

i dont understand

Answer 28

so you have an inequality which means there is more than one answer

Answer 29

oh ok

Answer 30

so in order to know which side you need to shade, you must pick a point on some side of the line to see if the point solves it or not

Answer 31

so try plugging in (0,0) and see if it makes the equation correct

Answer 32

i think you would shade in the left side

Answer 33

well you can be sure if you plug it in and see if (0,0) solves it or not

Answer 34

whats the outcome when you plug in (0,0)

Answer 35

?

Answer 36

ii dont know

Answer 37

plug in the point then to this inequality
(0,0) into y>2x+2

Answer 38

0>2(0)+2

Answer 39

just 2?

Answer 40

what do you mean?

Answer 41

you get 0>2 yes so that means it isn't correct so shade for that line the side opposite of (0,0)

Answer 42

now try the other line

Answer 43

ok

Answer 44

show me the line and where to shade and ill help if you need it

Answer 45

@Ednac

Answer 46

thats the first line, try the other one

Answer 47

also what grade is this in math?

Answer 48

your hot

Answer 49

yeah

Answer 50

prob 8 or 9

Answer 51

im 10 and age is 19

Answer 52

Ednac

Answer 53

@Ednac

Answer 54

i dont know this one
