Check my answers please?

That slope isn't even positive.

hero (hero):

How did you go about figuring out the slope?

OpenStudy (anonymous):

It's wrong :(

hero (hero):

lol, no it isn't

OpenStudy (anonymous):

look at the negative slopes

OpenStudy (anonymous):

you cant do that!

OpenStudy (anonymous):

-2/3

OpenStudy (anonymous):

D isn't even on top of 0

OpenStudy (anonymous):

that's why you can't do it

OpenStudy (anonymous):

change of y/ change x y2-y2/x2-x1

OpenStudy (anonymous):

y2-y1/x2-x1

OpenStudy (anonymous):

read what MC is saying

hero (hero):

You're not supposed to forget the basics

OpenStudy (anonymous):

take two points on the graph and try it

OpenStudy (anonymous):

no

OpenStudy (anonymous):

actually, that's not one, it's more like 1/2

OpenStudy (anonymous):

1 and a 1/2

OpenStudy (anonymous):

listen... slope is y2-y1/ x2-x1 take two points of the graph

OpenStudy (anonymous):

that'd be a negative slope!

OpenStudy (anonymous):

noo you look at points on the graph- TWO POINTS. Pick Two coordinates and put in the equation

hero (hero):

|dw:1360315712415:dw|

OpenStudy (anonymous):

I was just about to do that

OpenStudy (anonymous):

you said you wanted to check your answer yet you are arguing...

OpenStudy (anonymous):

ooh! Getting out of hand She left

hero (hero):

@Megan_xoxo is who wanted to check her answers

OpenStudy (anonymous):

uh huh...

OpenStudy (anonymous):

leave it alone, she's gone!

hero (hero):

lol, no she isn't

OpenStudy (anonymous):

why do my questions always end up in an argument :(

OpenStudy (anonymous):

what? she came back?

OpenStudy (anonymous):

ehh...not your fault

OpenStudy (anonymous):

anyways can someone help me i have no idea how to do this stuff...

OpenStudy (anonymous):

ok, the answer is B let's just clarify that

OpenStudy (anonymous):

now, if you follow MCJones technique you'll get the right answer

OpenStudy (agent0smith):

There's an easier way to get a slope from a graph than by picking two points and using the slope formula... do it visually. See the attached image. \[slope = \frac{ rise }{ run }\] How many units does it rise by from D to C? it drops 4, so the rise is -4. How many units do you then have to go across to meet the graph? 6.
