@driftracer305

OpenStudy (anonymous):

ok the question?

OpenStudy (oleg3321):

OpenStudy (oleg3321):

both of them

OpenStudy (oleg3321):

@SolomonZelman

OpenStudy (oleg3321):

@driftracer305

OpenStudy (anonymous):

well @oleg3321 listen...to find the slope of the function f(x) given two points (x1,y1) and (x2,y2) use this formula : \[\frac{ y2 - y1 }{ x2 - x1 }\]

OpenStudy (anonymous):

now imagine (x1,y1) = (-1,-9) and (x2,y2) = (1,7)

OpenStudy (anonymous):

now can u find the slope of f(x)?

OpenStudy (oleg3321):

no

OpenStudy (oleg3321):

not really

OpenStudy (oleg3321):

can you please give answer im in a hurry

OpenStudy (anonymous):

it would be (7+9)/(1+1) = 16/2 = 8

OpenStudy (anonymous):

so the slope of f(x) = 8

OpenStudy (anonymous):

It's better for u to understand the problem not just give the answer ;)

OpenStudy (oleg3321):

is that the first question or the second

OpenStudy (anonymous):

and for g(x) ... as it's in standard form (y = mx + b which m is slope and b is y-intercept) so the slope is 3

OpenStudy (anonymous):

all these explanations are for question 1

OpenStudy (oleg3321):

can you help me with second one too

OpenStudy (oleg3321):

please

OpenStudy (anonymous):

Ok...take it easy ;)

OpenStudy (anonymous):

and for question number 2 : first we should find y-intercept for f(x) ... well when x=0 then the value for f(x) would be the y-intercept : |dw:1406054400500:dw|

OpenStudy (anonymous):

and we have f(0) = -1 so the y-intercept is -1 too...and for g(x) , as i told u it has been written in standard form so -2 is the y-intercept for g(x) and -1>-2 so the y-intercept for f(x) is greater than the y-intercept for g(x) ;)

OpenStudy (anonymous):

@oleg3321

OpenStudy (oleg3321):

ya im here sorry

OpenStudy (oleg3321):

so whats the answer

OpenStudy (anonymous):

so they're already solved ;)

OpenStudy (oleg3321):

so the answer is? sorry i dont get it

OpenStudy (anonymous):

i explained it to u ;) let x=0 then f(x) or f(0) would be the y-intercept and y can see the value for f(x) in which x=0 in the table and it's -1 so the y-intercept for f(x) = -1 and for g(x) it's -2

OpenStudy (anonymous):

well now which of them is greater?

OpenStudy (oleg3321):

? :(

OpenStudy (precal):

@PFEH.1999 You are doing a great job explaining.

OpenStudy (precal):

@oleg3321 you really need to learn these concepts because math is only going to get harder if you can't do something basic like slope formula

OpenStudy (anonymous):

Thanks @precal ;)

OpenStudy (anonymous):

agree with @precal ;) think it's better for u to first practice the basics...such as finding y-intercepts...writing equations for lines...finding slopes and etc and then try to solve these ;)

OpenStudy (oleg3321):

can we continue the problem please

OpenStudy (oleg3321):

-1 is greater

OpenStudy (anonymous):

ok then...it's better for u to first find the y-intercept for g(x)...as it's in standard form (y=mx + b which m is slope and b is y-intercept.) so -2 is y-intercept...ok then?

OpenStudy (anonymous):

yes -1 is greater ;)

OpenStudy (oleg3321):

so what do you do next

OpenStudy (anonymous):

ok we have solved it ;)

OpenStudy (oleg3321):

so the answer is -2 and -1 @PFEH.1999

OpenStudy (anonymous):

yes and -1 is greater

OpenStudy (anonymous):

got it?

OpenStudy (oleg3321):

so -1 is greater than -2 is the answer

OpenStudy (anonymous):

yes and u can write how did u find this too.

OpenStudy (anonymous):

and u can write f(x) has the greater y-intercept too ;) well if you have understood u can write whatever the question wants :)

OpenStudy (oleg3321):

thanks human calculator hahaha ;)

OpenStudy (anonymous):

it's only a tag :D ur welcome ;)
