Question

Write the equation in slope-intercept form of the line that contains the points (4, -7) and (0, 5).

Answer 1

put the points (x1,y1) and (x2,y2) in the following equation:
(y-y1)/(y2-y1)=(x-x1)/(x2-x1)
then write in the standard form

Answer 2

@DeviousDill can u do it now?

Answer 3

I think i can 5-(-7)/0-4
5+7/-4
12/-4
-3

Answer 4

(y - -7) (x - 4)
------- = ------ 0_o
(5 - -7) (0 - 4)

Answer 5

I'm so confused right now. I haven't ran into these equations since 8th grade. I don't remember this stuff. -.-

Answer 6

am i correct

Answer 7

I don't know If you're correct, because I don't even know how to do it...

Answer 8

sorry,let me say

Answer 9

(y+7/12)=(x-4)/-4

Answer 10

hey plz look my answer n tell me if i am correct or not Sorous..

Answer 11

now we have to wtite it in the standard form
-4y-28=12x-48
12x+4y=-48+28
12x+4y=-20

Answer 12

It only says that i have to write the equation in slope intercept form that contains those points

Answer 13

the final answer: y=-3x-5

Answer 14

slope=-3
intercept=-5

Answer 15

@DeviousDill did u get it?

Answer 16

@keskerem sorry,did u see the solution?

Answer 17

I'm just so confused right now.

Answer 18

why?

Answer 19

u have to points and u want to find the equation of the line so u use that formula

Answer 20

Just about this whole thing. Solpe-intercept Equations....like how to find this answer. then the next question is...
Write the equation in slope-intercept form of the line that has a slope of -2 and y-intercept of 2.
I just don't get it

Answer 21

y=ax+b
a:slope
b:y-intercept

Answer 22

for an example u have slpoe( a=-2) and y-intercept(b=2)

Answer 23

y = -2x + 2 ?

Answer 24

so tellme wat is the line equation?

Answer 25

good

Answer 26

u r right

Answer 27

Write the equation in slope-intercept form of the line that has a slope of 3 and contains the point (2, 5).

so... 5 = -2(3) + 2 ?

Answer 28

no no

Answer 29

*facepalm*

Answer 30

wat does it mean?

Answer 31

Slap

Answer 32

uhum

Answer 33

Why the facepalm @DeviousDill ???

Answer 34

Cause i'm so confused. I get one, then I don't know how to do the next one. >_<

Answer 35

@DeviousDill i'll help u,don worry

Answer 36

for the next one u have to use this equation
y-y1=a(x-x1)
a=slope
point=(x1,y1)

Answer 37

I got the previous one, now I can't get this one...
Write the equation in slope-intercept form of the line that has a slope of 3 and contains the point (2, 5).

Answer 38

if your data is 2 point,u will use the first equation
if ur data is a slope and a point u will use the last formula

Answer 39

okay so,
y-5 = 3(x - 2)

Answer 40

good

Answer 41

so write in this form:y=ax+b

Answer 42

can u write?

Answer 43

no =/

Answer 44

y-5=3x-3*2
y=3x-6+5
y=3x-1

Answer 45

@DeviousDill ,is it clear?

Answer 46

Write the equation in slope-intercept form of the line that has a slope of 3 and contains the point (2, 5).

y-y1=a(x-x1)
y - 5 = 3(x - 2)
y - 5 = 3x - 6
+5 +5
y = 3x - 6 + 5
y = 3x -1
like that @sorour ?

Answer 47

right

Answer 48

so y = 3x - 1 is the answer?

Answer 49

yes

Answer 50

okay this next one is weird.

Answer 51

Using the slope-intercept method to graph this equation, in what order should these points on the line be drawn? 6(2x - 4y) = 3(2x + 4)
