Question

CAN SOMEONE PLEASE HELP ME FILL THIS PRACTICE SHEET OUT! I WILL MEDAL!

Please walk me through, from A,B to C.

Answer 1

@jabez177 Can you please help me?

Answer 2

It looks like you first need to isolate the y.
What can you do to get the y by itself?

Answer 3

No..sorry! I don't

Answer 4

what is on the left side by the y?

Answer 5

Is there another variable on the left side?

Answer 6

x+3y < 6
There is an x on the left

Answer 7

yes, what do you need to do to the x to move it to the right side?

Answer 8

Simplify?

Answer 9

? how would you simplify?

Answer 10

I don't know.
I really suck at this .-.

Answer 11

If it is positive, can you subtract it on both sides to move it?

Answer 12

yes

Answer 13

Do that

Answer 14

y = 6-x/3
Like that?

Answer 15

well, almost. You did a little more than just subtracting the x.
If you divide the 3, which you need to do, you must divide it by every thing
y = 6/3-x/3
y=2-x/3
or y=-3x+2

Answer 16

Can you see how that looks like y=mx+b

Answer 17

y=-3x+2
Yeah, okay

Answer 18

so if the y intercept=b, what number is b?

Answer 19

my mistake y= -x/3+2

Answer 20

x=3/y-2

Answer 21

no, don't move the x or y
y=mx+b
y= -x/3+2

what number is in the b spot?

Answer 22

+?

Answer 23

3?

Answer 24

if x=o what is y=

Answer 25

what number is after the plus?

Answer 26

2

Answer 27

yes. 2 is the y intercept. That is where one point is on your graph. If x=0 and y=2 how do you write them as an ordered pair?

Answer 28

Wait, I don't think we are supposed to solve it like that.
heere let me show you how I did it before, and what my teacher said about it.

Answer 29

yes, that is what you will do. I was just wanting to see if you knew how to write an ordered pair and which one was the x and y .
But look at the graph you just put up. Do you see the point on the (0,2)?

Answer 30

Yes..?

Answer 31

So that is the first point on your graph. Now lets see how to get the second one.

Answer 32

This is how I think the graph part should be

Answer 33

yes

Answer 34

Okay, good! Now, what should I write in part B and C?

Answer 35

B. what steps did you do to find the two points?

Answer 36

B.The line should be solid because it is less than or equal to.
^^ Like that?

Answer 37

Correct. Equal to means it does have to be solid. Why did you choose to shade under and not over?

Answer 38

C, it is shaded below the line because it is less than?

Answer 39

You got it. Good job

Answer 40

Can you help me with 1 more part?

Answer 41

What is that?

Answer 42

It should look something like this..

Answer 43

What does slope intercept form look like?

Answer 44

I'm not sure..

Answer 45

on part c in red there is an arrow pointing to it

Answer 46

y = ax+b ?

Answer 47

yes. Normally I see it written with an m not a.
Remember I wrote y=mx+b

Answer 48

So you need to do the same thing you did on the other problem to make this one loo like slope intercept form. What do you need to do to isolate the y?

Answer 49

I think I understand it.

y = 1/2x - 1
Slope-intercept form is y = mx + b...
4x - 8y = 8
8y = 4x - 8
y = 1/2x - 1

Answer 50

Well almost. try dividing everything by 4 first

Answer 51

4x - 8y = 8 * 4 x = 8 +2y

^^ like that?

Answer 52

4x - 8y = 8
x - 2y = 2
-2y = -x +2

Answer 53

Now isolate the y by dividing by what?

Answer 54

y= 2-x/-2

Answer 55

Not quite. You need to divide by -2

Answer 56

y = 2-x/2 <?

Answer 57

-2y = -x +2
y =-x/-2 + 2/-2

Answer 58

What does that come out to be?

Answer 59

x= 2(y+1)

Answer 60

You don't want to move the x and y

Answer 61

what is -x/-2?

Answer 62

y =-x/-3 <?

Answer 63

-/-=?

Answer 64

I honestly don't know. ;-; I'm sorry! I suck at math

Answer 65

what is -2 x -2 ?

Answer 66

0

Answer 67

neg times neg = ?
neg div neg = ?

Answer 68

-2 * -2 = 4

Answer 69

yes

Answer 70

so what is -x/-2?

Answer 71

4?

Answer 72

Where did 4 come from? you have a neg x being divided by a neg 2. You are looking at the two neg values. What does two neg values multiply or divide out to? It should come out as a positive value

Answer 73

I'm sorry, could you just show me how to do it..?

Answer 74

I am trying to show you how
if -d/-g= d/g
the neg div neg becomes posative

Answer 75

okay. so -x/-2 should = to 2x ?

Answer 76

almost. you wrote 2x (2 times x) that is not the same thing as x being divided by 2 is it?

Answer 77

My hour is up. I have to go. Maybe your teacher can explain it better.

Answer 78

Okay. Bye! I guess...
