Question

I hate math but it needs to get done sooooo help?

Answer 1

{y = -1/2x - 7
{y = 4x + 2

Answer 2

Solve each system of equations by graphing. Show all work on the attached paper. Use your solutions to navigate through the maze.

Answer 4

@dude

Answer 5

I have missed so many days I have no idea what to do here

Answer 6

Err so I guess you're doing this by hand?

Answer 7

Yep

Answer 8

Not home schooled anymore. Freshy in high

Answer 9

It's 22west btw

Answer 10

Oh, welcome back

Answer 11

Thx my mom told me to delete the other account so my techer would stop stalking me on it

Answer 12

Do you know how to graph functions at all? Or new to the process?

Answer 13

I used to until I had 37 missing assignments sooo..... We did a test today and I got none right...

Answer 14

D:

Answer 15

Yeahh...
56 in total

Answer 16

9 in english and 8 in media tech

Answer 17

Sooo

Answer 18

Ima have to redo freshman year

Answer 19

Thats ok

You should at least take the time to do your assignments on time <_<

Answer 20

Yeah
I think I've missed somewhere around 30 - 50 days

Answer 21

Okay lets actually get to the question

Lets start with the first equation given: \(y = -\dfrac12x - 7\)

This is slightly harder than the first which is also why I chose to start here

y-intercept is always the best point to start your graph with

Do you know what the y-intercept in the equation is?

Answer 22

No

Answer 23

The slope-intercept form is written as

\(y=mx+b\)

m is slope
b is y-intercept

Answer 24

Does that help

Answer 25

Yeah I remember that. But I have no idea what to do now.

Answer 26

I'm about to get in the shower sooo

Answer 27

Hmm you should really take more time to do your assignments

Just give me the value of the y-intercept based on the equation they gave you

Answer 28

I don't know the value of the y-intercept...

Answer 29

How do I find it?

Answer 30

I just showed you the general equation of a line

Answer 31

It's systems of equations.
I thought y-intercept was slope.

Answer 32

I'm better at English lol
I suck at math

Answer 33

Its asking you to graph each

y-intercept is not slope D:

Answer 34

Oh. Really? I thought we use y-intercept in slope

Answer 35

Using it **for** slope and it **being** slope are different things

Answer 36

And isn't y=mx+b slope intercept form?

Answer 37

\(\color{#0cbb34}{\text{Originally Posted by}}\) @dude
The slope-intercept form is written as

\(y=mx+b\)

m is slope
b is y-intercept
\(\color{#0cbb34}{\text{End of Quote}}\)

Yes.

Answer 38

Ohhhh

Answer 39

I'm so confused right now. I have a headache and this isn't helping but it is homework

Answer 40

\(y=~~~\color{red}{m} ~ x\color{blue}{+b}\)
\(y=\color{red}{-\dfrac12}x\color{blue}{-7}\)

You don't need to use brain cells for this

I've highlighted the slope and y-intercept here

m is slope
b is y-intercept

What is the y-intercept here?

Answer 41

-7

Answer 42

I'm going to take a quick shower brb

Answer 43

Right, thats all

Is the intercept in the x or y axis?

Answer 44

Bruh ._. ok

Answer 45

Back

Answer 46

Welcome back

Is the y-intercept on the x or y axis?

Answer 47

y axis right?

Answer 48

Yes

So the point would be (0, -7)

(You should have this)

Answer 49

I don't have a graph on the paper.

Answer 50

OH WAIT SHE GAVE ME A SEPARATE PRICE OF PAPER WITH GRAPHS ON IT

Answer 51

Lemme get it quick

Answer 52

`Show all work on the attached paper.`

Yeah

Answer 53

Got it

Answer 54

Now (just to make sure)

What is the slope in this equation?

Answer 55

-1/2x

Answer 56

Just the number, but yes

\(-\dfrac12\) or \(\dfrac{-1}{2}\) (You'll see why I wrote it like that in a bit)

Slope is \(\dfrac{rise}{run}\) (Did you learn about this?)

Answer 57

Yes but I hardly remember it

Answer 58

A friend told me the answer but I just need to work out the problem. It's (-2, -6) right?

Answer 59

There are 3 paths, (4, -6), (-2, -6), and (-2,1)

Answer 60

It's pretty straightforward, it shouldn't be too hard

Rise tells us how many units to move up/down [Positive numbers move up and negative move down]
Run tells us how many to move right/left [Positive numbers move right and negative numbers move left]


\(\dfrac{-1}{2}\) What direction is this slope going?

Answer 61

1 down 2 right

Answer 62

Good

So to do that, start at (-0,-7)

Move down 1 unit and 2 units right


To move in the opposite direction, move up 1 and left 2 [Reverse the order]

Answer 63

Done. Now the second formula right?

Answer 64

Yes, this should be easier

What is the y-intercept in \(y=4x+2\)?

Answer 65

2

Answer 66

So where would that point be?

Answer 67

(0,2)

Answer 68

Good (:

Answer 69

What is the slope?

Answer 70

4x

Answer 71

Just the number but yes

4 can also be written as \(\dfrac41\)

Answer 72

Okay

Answer 73

So either 4 or 4/1

Answer 74

I am using \(\dfrac41\) to make it easier to use rise/run, although once you get used to it, you dont need to re-write it

Answer 75

Okay

Answer 76

move up 4 move to the right 1

Answer 77

or down 4 to the left 1

Answer 78

So they intersect at (-2,-6)

Answer 79

Right

Answer 80

So that's the answer

Answer 81

And that is your only intersection

Answer 82

Ye

Answer 83

That problem is done. 1 down like 20 more to go

Answer 84

And I just lost my pencil YAY

Answer 85

Gimme a sec while I find my pencil in the dark

Answer 86

Alright found it. The next one is:
{y=x+2
{y=-3/5x-6

Answer 87

The answers are: (-5,-3), (-5,3), (-3,-5), (5,-3)

Answer 88

Make a new post, you should also try the process on your own or ask me if you are stuck

Answer 89

I will more than likely get stuck
