Question

here Choose the point-slope form of the equation below that represents the line that passes through the points (−6, 4) and (2, 0).

y − 4 = −one half(x + 6)

y − 4 = 2(x + 6)

y + 6 = −one half(x − 4)

y + 6 = 2(x − 4)

Question 2 (Multiple Choice Worth 2 points)

Given the equation y − 3 = one half(x + 6) in point-slope form, identify the equation of the same line in standard form.

x − 2y = −12

y = one halfx

y = one halfx + 6

y = one halfx + 9

Question 3 (Multiple Choice Worth 2 points)

Given the equation y − 4 = three fourths(x + 8) in point-slope form, identif

Answer 1

the other guy left idk why

Answer 2

OK what do you need to do first?

Answer 3

First you have to find the slope. Can you do that?

Answer 4

i have no clue mabe put the variables on one side

Answer 5

I'll be right back.

Answer 6

1. Find the slope using the formula y2-y1/x2-x1 with the given values of x and y.
2. Organize the equation into form y = mx + c after you have the x and y-intercepts.
3. The line equation you get will be your answer.

Answer 7

slope is the rtio of the change in y to the change in x.

Answer 8

OK @mikala1 what are the two points you're given?

Answer 9

6,4 and 2,0

Answer 10

(-6, 4) and (2, 0) right?

Answer 11

So those are the values you need to find the slope.

Answer 12

Yes so then if you compare the first y to the second y, what change has occurred? Has it increased or decreased and by how much?

Answer 13

it have derease

Answer 14

By how much?

Answer 15

2

Answer 16

NO! Look again.

Answer 17

what one are we talking about

Answer 18

5

Answer 19

If you compare the first y to the second y, what change has occurred? Has it increased or decreased and by how much?

Answer 20

what number is the second y

Answer 21

Every point is (x, y).

Answer 22

\[m=\frac{ y2-y1 }{ x2-x1}\]

Answer 23

i do not know because im not good with negitive numbers

Answer 24

The first point is (6, 4) and the second point is (2, 0). So what are the two y values?

Answer 25

4 and 0 right

Answer 26

First Of All You Need To Find The Slope
(x1,y1)=(-6, 4) And (x2,y2)= (2, 0).

Answer 27

@hba I know the formula. Thank you very much but I am trying to teach her so would you kindly allow me to continue? Thank you!!!

Answer 28

Oh I See,No Problem @calculusfunctions

Answer 29

Yes @mikala1 the two y's are 4 and 0 so what change has occurred from the first y to the second y?

Answer 30

4

Answer 31

Is that an increase or a decrease of 4?

Answer 32

decr4ease

Answer 33

Right so then we say that the change in y is -4. Do you understand so far?

Answer 34

some what but keep going

Answer 35

Now what are the two x coordinates?

Answer 36

is d the ansure just asking

Answer 37

-6 and 2

Answer 38

So then what change has occurred from the first x to the second x?

Answer 39

5

Answer 40

NO! try again.

Answer 41

9

Answer 42

hello

Answer 43

any one homee

Answer 44

NO! it's 8. Check again.

Answer 45

im sorry i was one off i am not good with - numbers

Answer 46

So then the change in y is -4 and the change in x is 8, correct?

Answer 47

i think so sure if you say yes

Answer 48

The slope of a line m = (the change in y)/(the change in x) which is what @hba was telling you by rudely interrupting.

Answer 49

So now @mikala1 can you tell me what the slope would be?

Answer 50

umm d

Answer 51

hello any one there i only have 10 min left plz

Answer 52

Yes @mikala1 so the slope is m = -4/8 = -1/2. Do you understand?

Answer 53

yes ssssure can we move on now plz im running out of ttime

Answer 54

i only have 5 min left sorry to rush u

Answer 55

the seond on is b right

Answer 56

is any one here still

Answer 57

OK now the equation of a line is y = mx + b so now we know that m = -1/2. So now we use one of the points, let's say (-6, 4) and solve for b. I'll just show you since you're running out of time. x = -6, y = 4, m = -1/2 thus

4 = (-1/2)(-6) + b

4 = 3 + b

b = 1

∴ y = (-1/2)x + 1

Which is the same as answer a). Understand? Sorry I didn't want to just end up giving you the answer but you're saying you're in a rush plus this @hba guy shows no respect for anyone so it is not making my job easier.

Answer 58

im sorry its just my math class is over in 2 min and i neede help thank you so much for your time

Answer 59

that is all for now thank you
