Please help with Math?? I will fan and medal

@sleepyjess

OpenStudy (hypersniper445):

i can choose more than one

OpenStudy (mehek.15):

y = mx + b m = slope b = y-intercept so if 9/4 is slope and -14 is yintercept what equation

OpenStudy (hypersniper445):

how do i find that

OpenStudy (mehek.15):

well your problem says 9/4 is the slope so put that for m y = 9/4x + b the y-intercept is -14 put that for b y = 9/4x - 14

OpenStudy (hypersniper445):

so C

OpenStudy (mehek.15):

so that means C is one answer now we need to see if the others are correct as well

OpenStudy (hypersniper445):

D can't be correct because it is positive

OpenStudy (mehek.15):

so either A or B

OpenStudy (hypersniper445):

A?

OpenStudy (mehek.15):

yes A so A and C are the answers

OpenStudy (hypersniper445):

do you have time for more?

OpenStudy (mehek.15):

sure

OpenStudy (hypersniper445):

A line has a slope of 3 and contains the point (−1, −8). Which equations represent the line? Choose all answers that are correct. A. −3x + y = −5 B. 3x + y = −5 C. (y – 8) = 3(x − 1) D. (y + 8) = 3(x + 1)

OpenStudy (mehek.15):

you can plug in the ordred pair and see which ones are true put -1 for x and 8 for y

OpenStudy (hypersniper445):

A?

OpenStudy (mehek.15):

ye A is true any others?

OpenStudy (hypersniper445):

D?

OpenStudy (mehek.15):

ye D is correct as well

OpenStudy (hypersniper445):

i think that is it

OpenStudy (mehek.15):

so A and D

OpenStudy (hypersniper445):

this one will come in parts

OpenStudy (hypersniper445):

OpenStudy (mehek.15):

first , is the slope positive or negative?

OpenStudy (hypersniper445):

positive

OpenStudy (mehek.15):

so positive slope = line goes up

OpenStudy (hypersniper445):

they are all positive

OpenStudy (mehek.15):

oke so since all are positive, look for the y-intercept

OpenStudy (hypersniper445):

So A or D since they both intercept y= -2

OpenStudy (mehek.15):

right so it can be o

OpenStudy (mehek.15):

one of those

OpenStudy (hypersniper445):

I think it is D

OpenStudy (mehek.15):

now we look at the slope of both of them

OpenStudy (mehek.15):

well lets see if D is correct

OpenStudy (hypersniper445):

okay

OpenStudy (mehek.15):

using (3,-1) and (0,-2) \(\dfrac{-2-(-1)}{0-3}=\dfrac{-1}{-3}=\dfrac{1}{3}\) so D it is

OpenStudy (hypersniper445):

okay thats what i thought

OpenStudy (hypersniper445):

OpenStudy (mehek.15):

which one do you think?

OpenStudy (hypersniper445):

C

OpenStudy (mehek.15):

ye C is corrct

OpenStudy (mehek.15):

I gtg

OpenStudy (hypersniper445):

oh okay. i have to ask, are you like an alt account of Mehek14? because there is no way you are this smart with only 10 smart score
