A.

OpenStudy (anonymous):

1/3

OpenStudy (anonymous):

no its c

OpenStudy (anonymous):

I'll prove it

OpenStudy (anonymous):

got it?

OpenStudy (anonymous):

it definetly is a

OpenStudy (anonymous):

ok I will explain. to find the slope on a graph you need to find any two points that the line crosses through perfectly so I picked (-1,3) and (0,6). To find the slope you must put in standard form. So y2-y1/x2-x1. The x would be the first number in the coordinates and y is the one on the right. So u pick a point and you should have (-1 =x1 and 3=y1) and (0=x2 and 6=y2) so then u solve and u should get 3/1 which equals 3. Got it?

OpenStudy (anonymous):

sure

OpenStudy (anonymous):

I'm not positive but I think its d. that 1 was a little difficult for me. lol any more

OpenStudy (anonymous):

yes. it's D. 5-8 / 9-3 = -3 / 6 = -1/2

OpenStudy (anonymous):

I'd love to :)

OpenStudy (anonymous):

ok go ahead

OpenStudy (anonymous):

3.4-11.4 / -3.1- (-7.1) = -8 / 4 = -2 So B.

OpenStudy (anonymous):

b

OpenStudy (anonymous):

yep

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

Do you know what the first step is?

OpenStudy (anonymous):

do you know the formula?

OpenStudy (anonymous):

y2-y1 / x2-x1

OpenStudy (anonymous):

oh are you working on the one from before?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

hey u learned something from y2-y1/x2-x1... lol

OpenStudy (anonymous):

now what do you do? finish it

OpenStudy (anonymous):

got to go srry but u can do it!!! good luck!!! I am truly srry!!!

OpenStudy (anonymous):

its alright @jacesolano2795 thank you for helping!

OpenStudy (anonymous):

keep it as fractions

OpenStudy (anonymous):

positive 7/3

OpenStudy (anonymous):

yes! now divide

OpenStudy (anonymous):

13/3 divided by -9/2 ?

OpenStudy (anonymous):

It is an answer

OpenStudy (anonymous):

I don't know what you are doing...

OpenStudy (anonymous):

when you divide 2 fractions you multiply by neg reciprocal. so 13/3 * -2/9 = ?

OpenStudy (anonymous):

26/27 thank you! @nadialabish94

OpenStudy (anonymous):

umm no.

OpenStudy (anonymous):

but your welcome!

OpenStudy (anonymous):

- * + = -

OpenStudy (anonymous):

you multiplied a positive and a negative so the answer has to be negative. but other than that youre great :)

OpenStudy (anonymous):

yey, thank you!

OpenStudy (anonymous):

YES! you did it!

OpenStudy (anonymous):

Listen, if you ever need help with school work just message me. I'm pretty much always here. If you want or need to talk too I'm here

OpenStudy (anonymous):

That means a lot, thank you so much! @nadialabish94

OpenStudy (anonymous):

I mean it!
