Question

is this correct ?

Write the equation of the line passing through the points (0, -4) and (-2, 2).

Answer 1

m= 6 - (-4)/ -2 - 0 = 10/ -2 = -2

y - (-4) = -2 (x-0)

y + 4 = -x + 0

y + 4 - 4 = -x + 0 - 4

y = (-x )-5

Answer 2

where did the 6 come from?

Answer 3

Whre is your 2x?

Answer 4

Yes, also where did the 6 come from?

Answer 5

srry srry thats for another question

Answer 6

m= 2 -(-4)/ -2 - 0 = 10/ -2 = -2

y - (-4) = -2 (x-0)

y + 4 = -2x + 0

y + 4 - 4 = -2x + 0 - 4

y = (-x )-5

Answer 7

Where did your -2x go in your final answer? How did you get (-x)?

Answer 8

m= 2 -(-4)/ -2 - 0 = 10/ -2 = -2

y - (-4) = -2 (x-0)

y + 4 = -2x + 0

y + 4 - 4 = -2x + 0 - 4

y = (-2x )-5

Answer 9

And how did you get -5 if you subtracted 4?

Answer 10

srry my keyboard is a lil messed up

Answer 11

@Untamed_Being You need to write down the formula first, then plug the numbers in

Answer 12

m= 2 -(-4)/ -2 - 0 = 10/ -2 = -2

y - (-4) = -2 (x-0)

y + 4 = -2x + 0

y + 4 - 4 = -2x + 0 - 4

y = (-2x )-4

Answer 13

again... where did you get the 10 from

and 10/-2 is not -2

Answer 14

@Chlorophyll i did

Answer 15

@completeidiot please leave the convo

Answer 16

Yes, it should be 6. Not 10.

Answer 17

Slope formula:
m = ( y2 - y1) / ( x2 - x1)
= ( 2 + 4) / -2

Answer 18

m= 2 -(-4)/ -2 - 0 = 6/ -2 = -2

Answer 19

m = 6/ -2 = .... ?!?

Answer 20

@Untamed_Being It'll be pointless to go through the whole process when you's already wrong at the first line!

Answer 21

im following the lesson on my notebook @Chlorophyll

Answer 22

Plug those values into the point-slope formula, y - y1 = m(x - x1).

y - 3 = -1(x - 2)

y - 3 = -x + 2

y - 3 + 3 = -x + 2 + 3

y = -x + 5

Answer 23

Your basic arthmetic is totally off !!!
2 + 4 = 6 ( not 10 !)
6/ -2 = ....?

Answer 24

i've already said my keybaord is messed up

Answer 25

Then what's the right value of m now???

Answer 26

ok this is my question

Write the equation of the line passing through the points (0, -4) and (-2, 2).

m= 2 -(-4)/ -2 - 0 = 6/ -2 = -2

Answer 27

is it -2 ?

Answer 28

So you can't do 6/2 = ?

Answer 29

thats a fraction though

Answer 30

6
--
2

Answer 31

\[6 \div 2\]

Answer 32

6 /2 is 3

Answer 33

ok so then 6/-2 =?

Answer 34

so it would be m= 2 -(-4)/ -2 - 0 = 6/ -2 = -3

Answer 35

Now, don't blame your keyboard anymore !!!

Answer 36

@completeidiot Thank you for offering your shoulder :)

Answer 37

@Untamed_Being Are you positively m = -3 now?

Answer 38

yes

Answer 39

Then, proceed to plug it in POINT-SLOPE form:

Answer 40

y - (-4) = -3 (x-0)

y + 4 = -3x + 0

y + 4 - 4 = -3x + 0 - 4

y = (-x )-4

Answer 41

Yes, to make it less confused:
y + 4 = -3x
y = -3x - 4

Answer 42

so i did it correctly

Answer 43

I don't know why you keep the zero, and also why you drop 3 in front of -x

Answer 44

less confusing for me that way srry

Answer 45

y = -3x - 4 ( NOT y = -x - 4)

Answer 46

y - (-4) = -3 (x-0)

y + 4 = -3x + 0

y + 4 - 4 = -3x + 0 - 4

y = -3x - 4

Answer 47

You can only subtract constant to constant, nothing involve with x term or y term!

Answer 48

got it
