Question

Could someone explain to me graphing linear equations and inequalities?

Answer 1

Sure I will!

Answer 2

Thankkk you

Answer 3

http://www.purplemath.com/modules/ineqlin.htm here Is a liink were are int he info is

Answer 4

I do online school and my math teacher is in California and I'm in turkey, so theres a big time difference, and he asks me to stay up at 4 am to do an iclass to help me on said subject, when I did last night, he bailed last minute so I'm annoyed and confused about this topic

Answer 5

He linked me to that website but I have no interest in website because they are useless to me

Answer 6

aaa i see OH and I almost forgot there is a Video too so you can se how hat teacher does all of it hope you enjoy it and have a great day!

Answer 7

I already watched 6-8 videos and none of which helped me since I have questions

Answer 8

But thank you~ c:

Answer 9

what part of the topic do you need the help with?

Answer 10

That is the topic, literally. I have no idea about anything on it

Answer 11

@mathmale

Answer 12

you should have gone over how to plot points, or make a table of points to plot by this stage

Answer 13

maybe if you had a more specific example to work with?

Answer 14

a line can be constructed it we know at least 2 points on the line. plot the points and draw the line between them.

the inequality construction uses the line as a boundary and shades a side that contains points that make it true

Answer 15

But I just.. I don't know how to make a graph based on a question. I might know, but I'm confused about it. Should I post an example here from my lesson?

Answer 16

Ok.

Answer 17

Basically, imagine a grid.

Answer 18

is there a specific problem that we can work with? that might help out some.

Answer 19

yes, post an example from your lesson

Answer 20

01.05 Writing the Equation of a Line

Answer 21

Is what its called

Answer 22

Write the equation of the line passing through (2, -1) with a slope of 2 in standard form.

Answer 23

Take a look at this: https://www.youtube.com/watch?v=nJG-l2xhcYE.

Answer 24

there are many formats of a line equation, the format called point slope uses the slope and a point to create the parts of the equation with

Answer 25

That will explain graphing linear equations.

Answer 26

from there its just reworking it into standard form.

what does your material give you for the point slope formula?

Answer 27

The standard form of a linear equation is ax + by = c, where a, b, and c are integers and a is also positive.
The slope-intercept form of a linear equation is y = mx + b, where m represents the slope and b is the y-intercept.

Answer 28

slope intercept, we dont have an intercept, only a point in general

Answer 29

point slope format, it might be called slope point format but that just sounds wierd to me

Answer 30

What if you were given the slope and a point on the line, but not the y-intercept? Don't worry, there is one more form you can use. The point-slope form of a linear equation is y – y1 = m(x – x1). The variable m still represents the slope of the line while (x1, y1) is an ordered pair of any point on that line.

Answer 31

Pfff I'm sorry

Answer 32

good lets use that one

Answer 33

y – y1 = m(x – x1).

Answer 34

WHY ARE THERE QUESTION MARKS

Answer 35

lets use the point (a,b)

y-b = m(x-a)

Answer 36

the site has some encoding issues lately that doesnt interpret certain inputs

Answer 37

if youare copy pasting, then you are most likely to get the black diamond marks

Answer 38

Launch Area:___(1, 2)___
Point A:___(0, 3)___
Point B:___(-3, 0)___
Point C:___(-1, -4)___
Graph the coordinates of the specifics points in space your spacecraft will travel to.
You must show your work on each question below.

Determine the equation of the line, in standard form, that will get your spacecraft from the Launch Area to Point A.

Determine the equation of the line, in point-slope form, that will get your spacecraft from Point A to Point B.

Determine the equation of the line, in slope-intercept form, that will get your spacecraft from Point B to Point C.

Convert the equation you arrived at in question 2 into slope-intercept form. Make sure to include all of your work.

Reflect back on this scenario and each equation you created. Would any restrictions apply to the domain and range of those equations? Explain your reasoning using complete sentences.

Submit your graph and responses to questions 1 through 6 to your instructor as 01.05 Writing the Equation of a Line.

Answer 39

Okay thats my assignment that I have to do but all the Point A to point B is confusing me...

Answer 40

lets fill in the specifics into the point slope format to get started:

(a,b) = (2, -1): m=2

y - 2 = 2(x+1)

Answer 41

your assignment will require you to find the slope between 2 points, and also to utilize the different line formats

Answer 42

Answer 43

This is a really annoying thing especially since my teacher bailed out on me.

Answer 44

y - 2 = 2(x+1)

lets work this out int y=mx + k, slope intercept form

y = 2x +2+2

y = 2x + 4

now we can work thhis pretty easily into standard form

Answer 45

2x + y = 4?

Answer 46

almost ... lets subtract 2x from each side, then multiply thru by -1

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



-(-2x+y = 4)

2x-y = -4

the last step is just to get the leadinng x term positive

Answer 47

OH I forgot that whenever I put a number to the other side of the equal sign, it has to be negative

Answer 48

thats why you need to do math instead of 'moving'

Answer 49

if we subtract 2x from each side, we have moved nothing. we have simply performed a valid operation that keep both sides equal

Answer 50

So could you help me with this assignment? Like what am I supposed to do?

Answer 51

yes, the only thing i see we need to know are formats, and how to find the slope between 2 points

Answer 52

formats are easy enough, now what the format looks like and math one form into another.

how would you find the slope between 2 points tho? since this is an important part of any line equation.

Answer 53

I dont know what you mean

Answer 54

?

Answer 55

if given 2 points, how do we determine the slope between them?

Answer 56

your material should have a slope formula in it to work with.

Answer 57

Launch Area:___(1, 2)___
Point A:___(0, 3)___
Point B:___(-3, 0)___
Point C:___(-1, -4)___

Answer 58

Please ignore the name I only put that name so I could find it in my downloads

Answer 59

plot the point for A

Answer 60

With what program though ?

Answer 61

just use the draw feature we have. and do your best to make a rough sketch

Answer 62

I'm sorry if I seem retarded or stupid I just was wondering..

Answer 63
