Question

Find the value of x so that the line passing through (x, 10) and (-4, 8) has a slope of

Answer 1

oops

Answer 2

2/3

Answer 3

@misty1212 my bad!

Answer 4

ok ok now now we can get somewhere
the slope is found by computing
\[\frac{y_2-y_1}{x_2-x_1}\]

Answer 5

how would i do hat without x

Answer 6

\[\frac{10-8}{x+4}=\frac{2}{3}\]

Answer 7

wait how'd you get 3 from the 4+x?

Answer 8

you gotta find the \(x\) but you can probably figure it out without using algebra

Answer 9

can u explain

Answer 10

you said the slope was \(\frac{2}{3}\) right?

Answer 11

oh right

Answer 12

so i computed the slope using the formula and put it equal to 2/3
the only number we do not know is x

Answer 13

i hope that explains this line \[\frac{10-8}{x+4}=\frac{2}{3}\]
you still need to find x

Answer 14

but it is now pretty easy
\[\frac{10-8}{x+4}=\frac{2}{3}\\
\frac{2}{x+4}=\frac{2}{3}\] so
\[x+4=3\] and then you find x

Answer 15

the 2nd step to the third kinda threw me off

Answer 16

\[\frac{2}{x+4}=\frac{2}{3}\\
x+4=3\]? that part?

Answer 17

ooh look at all the ghosts, must be halloween

Answer 18

why does the site do that?

Answer 19

i was wondering what is that???

Answer 20

idk

Answer 21

do u guys know what it is // why

Answer 22

ghosts of openstudy past maybe

Answer 23

Thought it was my browser, guess not

Answer 24

but about the math yes that part

Answer 25

yeah same

Answer 26

could it be the site checking up

Answer 27

you are thinking like a confused math student not a person that is why (not to be rude or anything)

Answer 28

\[\frac{2}{x+4}=\frac{2}{3}\] the top of both is 2 right?

Answer 29

since the numerators are both 2, the only way for them to be equal is if the denominators are both 3

Answer 30

yes

Answer 31

ok

Answer 32

sorry I'm stupid

Answer 33

lol no not stupid, just so stuck on the other stuff that you miss the totally obvious

Answer 34

math class has a way of doing that to otherwise completely intelligent people

Answer 35

very true

Answer 36

what would be the value of x? @misty1212

Answer 37

\[x+4=3\\
x=?\]

Answer 38

-1

Answer 39

bingo

Answer 40

thank u for all your help @misty1212

Answer 41
