Question

Which is the equation of the given line in slope-form?

A) y+4=9/8(x+1)
B) y+1=8/9(x+4)
C) y+1=8/7(x+4)
D) y-1=8/9(x-4)

Answer 1

do u know how to find slope?

Answer 2

in the graph u have 2 points..with that u can find the slope..

Answer 3

the slope is 6/9

Answer 4

no..check the numerator again

Answer 5

I keep getting y - 1 = (6/9)(x + 4) which is none of the answer choices >:(

Answer 6

\[\frac{ 3-(-1) }{ 1/2-(-4) }\]

Answer 7

what will u get on simplification

Answer 8

@jinxhead20 ?

Answer 9

im here hold on...

Answer 10

ok

Answer 11

I got 8/9 o-o

Answer 12

@priyar ????

Answer 13

8/9 is correct..now u know the slope..so write in one-point and slope form

Answer 14

so.. what do you get?

Answer 15

hold on...

Answer 16

@jinxhead20 ?

Answer 17

ok tbh i have no idea what to do now..

Answer 18

i think the answer is b

Answer 19

@priyar

Answer 20

one point and slope form is nothing but what used the first time when u got slope=6/9

Answer 21

its (y-y1)=m(x-x1)

Answer 22

here (x1,y1) is any of the two points..choose any one and substitute ..

Answer 23

we will choose (-4,-1)
so we will get
(y-(-1))=8/9 (x-(-4))
simplify this..

Answer 24

@jinxhead20 can u do that?

Answer 25

yeah

Answer 26

sorry for being stupid. I hate math.

Answer 27

its ok..math is a nice subject..take your time to understand it..only if u understand you will enjoy it..

Answer 28

so..what do u get ? which option is it?

Answer 29

d....

Answer 30

no..check again remember -(-1) is +1

Answer 31

can u pls be a bit faster..

Answer 32

@jinxhead20 ?

Answer 33

ok b! It is the only other answer with the 8/9 slope. IDK

Answer 34

you are correct! but u understood how the full eq came right?

Answer 35

-*- = +

Answer 36

yeah....

Answer 37

Thanks :)

Answer 38

ok.. u r welcome!
