D because...

OpenStudy (sleepyjess):

Ok, so for the first function, we have to put it in slope-intercept form again

OpenStudy (sleepyjess):

@some.random.cool.kid I love your picture ^_^

OpenStudy (some.random.cool.kid):

thanks

OpenStudy (sleepyjess):

@Lolafire , can you put the first one in slope intercept form?

OpenStudy (some.random.cool.kid):

this will most likely be D because when you are solving all of them you will notice that the rate of change from the graph is the highest but first like jess said put this in intercept form.

OpenStudy (sleepyjess):

Actually, it isn't D

OpenStudy (anonymous):

lol i ike your picture too and i got y=2x-4

OpenStudy (sleepyjess):

Yes!

OpenStudy (sleepyjess):

So what is the slope of that one?

OpenStudy (anonymous):

2

OpenStudy (sleepyjess):

Yep, what about the 2nd one?

OpenStudy (anonymous):

in slope form ?

OpenStudy (sleepyjess):

It is already in slope-intercept form

OpenStudy (anonymous):

5 ?

OpenStudy (sleepyjess):

Yep

OpenStudy (sleepyjess):

Ok, for the 3rd one, are you familiar with the slope formula?

OpenStudy (anonymous):

(1,3) (2,8)

OpenStudy (sleepyjess):

Ok, we will use those points. The slope formula is \(\sf\dfrac{y_2-y_1}{x_2-x_1}\). So substitute those points in and we have \(\sf\dfrac{8-3}{2-1}\)

OpenStudy (sleepyjess):

Oh woah woah woah you used 2 x-coordinates as a point and 2 y-coordinates as a point. 1 x and 1 y per point

OpenStudy (sleepyjess):

The points should be 1, 2 and 3, 8

OpenStudy (sleepyjess):

You here?

OpenStudy (anonymous):

yeah i got the answer but ill be back later i gtg ill just tag you in other questions
