still working on these ones eh?
OpenStudy (anonymous):
the formula
y2-y1/x2-x1
OpenStudy (anonymous):
yea
myininaya (myininaya):
you have (x1=6,y1=0) and (x2=4, y2=8)
just plug em in
OpenStudy (anonymous):
so, would y1 be 6, and y2 be 0?

would the answer be m=-1.5?
myininaya (myininaya):
you could choose (x1=6,y1=0) and (x2=4, y2=8)
or
you can choose (x2=6,y2=0) and (x1=4,y1=8)
myininaya (myininaya):
no try again
myininaya (myininaya):
let me see you plug them into formula
don't do anything else except plug them in

ok so after performing the operation on top you get=?
and after performing the operation on bottom you get=?
OpenStudy (anonymous):
m=2?
myininaya (myininaya):
are you sure its just 2?
myininaya (myininaya):
is 4 greater than 6? yes
so when you do 4-6 you get?
myininaya (myininaya):
oops the first question answer is no lol

8-0=8
4-6=-2
so what is 8/(-2)=
OpenStudy (anonymous):
-2?
myininaya (myininaya):
-2*?=8
myininaya (myininaya):
-4?
OpenStudy (anonymous):
ok,-4

-2*(-2)=4 not 8
OpenStudy (anonymous):
ok, so the answer is 4
myininaya (myininaya):
no
OpenStudy (anonymous):
@tc1979 u r great in division
OpenStudy (anonymous):
8/(-2)=-4

myininaya (myininaya):
right!
OpenStudy (anonymous):
yup
OpenStudy (anonymous):
so the answer is -4
myininaya (myininaya):
yes
you may need to work on your subtraction and division though if you want to get good at these
OpenStudy (anonymous):
so the slope is -4? that doesent make any sense

OpenStudy (anonymous):
usually slopes are in the form of a fraction
OpenStudy (anonymous):
use sense
myininaya (myininaya):
\[\frac{8-0}{4-6}=\frac{8}{-2}=-4\]
-4 is a fraction -4/1
OpenStudy (anonymous):
well this one is -4/1 so it is still a fraction, but it is written in a different form. but you're right, most of the time it is a fraction
OpenStudy (anonymous):
so I can put -4 and it will be considered a fraction?

myininaya (myininaya):
you would write -4 since -4/1 is -4 lol
myininaya (myininaya):
i don;t know anymore
this is getting too complex for me
lol
OpenStudy (anonymous):
yep, if you write -4 it is a legitimate form of input
myininaya (myininaya):
