hello Ms brains

OpenStudy (anonymous):

What's the answer @ethan726 do u know how to do it

OpenStudy (anonymous):

@Ms-Brains

OpenStudy (yamyam70):

What subject is this?

MsBrains (ms-brains):

Sorry, give me a moment. I am helping someone right now. I will have to examine the problem.

OpenStudy (anonymous):

Ok thanks so much

OpenStudy (anonymous):

It's algebra @yamyam70

MsBrains (ms-brains):

I'm not sure, But I'm thinking D. What do you think it is?

OpenStudy (anonymous):

I'm not sure

OpenStudy (yamyam70):

rate of change is the slope of a given function. i slope is calculating the rise of y(vertical) and the run of x(horizontal) the formula is: m = slope m = Rise / Run m = ( y2-y1) / (x2-x1)

OpenStudy (anonymous):

Alright I think I got that

OpenStudy (yamyam70):

you should first draw the graph and get the values of y axis. or go with trial and error(like put values of y chronologically

OpenStudy (yamyam70):

because x values are already given, goodluck!

OpenStudy (anonymous):

Thank you so much

OpenStudy (anonymous):

Ok so I'm pretty sure it's not b

OpenStudy (anonymous):

@yamyam70 is it D

OpenStudy (baru):

\[\frac{ f(15)-f(3) }{ 15-3 }\]

OpenStudy (anonymous):

@baru is it D

OpenStudy (anonymous):

Await no it's b

OpenStudy (baru):

can you show the steps you followed?

OpenStudy (anonymous):

i subtracted 15-3 and got 12 so that's B am I right?

OpenStudy (anonymous):

@baru

OpenStudy (anonymous):

Is it B @yamyam70 @baru

OpenStudy (anonymous):

Is it B @confxsedaf
