Question

Standard form ??? someone knows about it?

Answer 1

did u figure it out? if not the form would be Ax + By = C

Answer 2

Pont A: (1, 2)
Point B (0, 3)
Determine the equation of the line, in standard form from the point A to Point B. ??

Answer 3

can you help me?

Answer 4

ya sure just hold on a minute

Answer 5

ok so think of point A like this: (x1,y1) and point B like this: (x2,y2)

to find the equation of any line, you would first have to find the slope using m= y2-y1 / x2-x1

Answer 6

this website is helpful as well if you are confused by my explanation http://coolmath.com/algebra/08-lines/06-finding-slope-line-given-two-points-01.htm

Answer 7

y1 would be 2 because your point A (1,2) (x1,y1)

Answer 8

sorry , wrong questin lol

Answer 9

let me think just a min

Answer 10

ok sure, no problem

Answer 11

then what would be the standard form for this one?

Answer 12

well first you have to find the equation of the line then you can put it into standard form

Answer 13

once you find the slope put it into this equation y=mx+b m=slope

Answer 14

you can use either point A or Point B for x and y to find the "b"

Answer 15

did you find the slope yet?

Answer 16

it should be -1

Answer 17

yeep, i got it

Answer 18

so what i have to do now?

Answer 19

ok good. now put either point a or b into this formula: y=mx+b to find b.

Answer 20

y=-1x+b .. so B= y-x ?

Answer 21

um close. if you use Point A (1, 2) you would write the equation like this: 3=(-1)(1) + b
if you use point B (0,3) you would write it as 2 = (-1)(0) + b then solve for b

Answer 22

oops i meant the opposite, soorry

Answer 23

use point A 2= (-1)(0) + b and point B 3= (-1)(1) + b

Answer 24

i have to use both?

Answer 25

no just one. whichever one you like.

Answer 26

So .. 2=(-1)(0) + b . B=2 right?

Answer 27

oh my gosh im so sorry. i messed them up again. the equation should be 3=(-1)(0) + B

Answer 28

for point B

Answer 29

use this equation

Answer 30

so b=3 ?

Answer 31

yes correct.

Answer 32

so now write the equation again with only m and b having values

Answer 33

y=mx + b would turn into y=(-1)x + 3

Answer 34

then now you can finally put it into standard form Ax + By = C

Answer 35

try to keep A always positive and make sure it never has a fraction for future problems

Answer 36

But i dont have A , I just have the slope and b

Answer 37

i'm confused. i'm really bad in math lol

Answer 38

yes thats right but A has x in it so that would be your slope. you would bring the -1x to the left side of the equation. and your C you be your b,. y=-1x + 3 would be 1x + y = 3

Answer 39

does that make sense?

Answer 40

yeep, now i got it.

Answer 41

so my Standard form would be 1x+y=3 ?

Answer 42

kk glad i could help :)

Answer 43

thaaaank you so much

Answer 44

and yes that you be your answer

Answer 45

thank you! :)))
