HELP WILL FAN AND GIVE MEDAL

OpenStudy (anonymous):

What do ya need?

OpenStudy (oleg3321):

OpenStudy (oleg3321):

both of those questions

OpenStudy (oleg3321):

and im in a hurry

OpenStudy (anonymous):

Ok

OpenStudy (anonymous):

@anteater can you help with this too?

OpenStudy (anteater):

Looking

OpenStudy (anteater):

For your function g(x) = 3x - 2 do you know what the slope of that linear function is?

OpenStudy (anonymous):

@anteater Brb getting called

OpenStudy (anteater):

Sure. Hint, slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept.

OpenStudy (anteater):

So, for g(x) or y = 3x - 2 what would the slope be?

OpenStudy (oleg3321):

hey guys i just need help with number 2

OpenStudy (anteater):

Oh, ok! For g(x) = 3x - 2, the slope is 3 and y-intercept is -2, correct?

OpenStudy (anteater):

Now, looking at the chart that has data for the other linear function, what is the y-intercept there do you think?

OpenStudy (anteater):

Since the y-intercept is the value that you get for y when x is 0.

OpenStudy (anteater):

Looking at the chart, when x = 0, what is y?

OpenStudy (anteater):

or f(x)

OpenStudy (anteater):

Since y = f(x)

OpenStudy (anteater):

When x = 0, f(x) = f(0) = -1 , so the y-intercept for the linear function f(x) is -1 And they want to know which is bigger, that number or the y-intercept for your other function g(x). The y-intercept for g(x) was -2. So, which is greater, -1 or -2?

OpenStudy (oleg3321):

-1

OpenStudy (anteater):

Yes :)

OpenStudy (anteater):

And what did you find for the slope of f(x) by the way?

OpenStudy (oleg3321):

so the answer is -1 is greater that -2

OpenStudy (anteater):

Yes, since -1>-2, the y-intercept of f(x) is larger than the y-intercept of g(x)

OpenStudy (oleg3321):

thanks

OpenStudy (anteater):

Wlcm

OpenStudy (anteater):

Did you find the answer to part A?

OpenStudy (oleg3321):

yes thanks ill message you cause i have more questions

OpenStudy (anteater):

Actually, I have to go now, since I have an appointment.

OpenStudy (anteater):

But ganeshie is a good one to ask!

OpenStudy (anteater):

And I think he is on right now. :)

OpenStudy (anteater):

Actually mathmate is on. Also good.

OpenStudy (anteater):

So I wish you luck with your work! And have a good afternoon.
