Use the slope formula: y2-y1/x2-x1, that will give you the slope of the line
OpenStudy (anonymous):
ok thanks
OpenStudy (anonymous):
i keep getting -2

basically I'm asking what is 6-1?
OpenStudy (anonymous):
5
myininaya (myininaya):
what is the change of x?
i'm asking you here to do do 1-(-2)?
OpenStudy (anonymous):
Try again @destinistmyers, it's not -2

slope is the change of x over y
OpenStudy (anonymous):
Well thank you for your help
OpenStudy (anonymous):
hope that helps you
you're welcome

slope if change of y over change of x
@jtryon
myininaya (myininaya):
is not if

oh, I had it backwards... you are right @myininaya
OpenStudy (anonymous):
So it would be 3/5?
OpenStudy (anonymous):
no, it doesn't change the answer
OpenStudy (anonymous):
it is still 5/3 because when you work the problem, the slope you get is 5/3
OpenStudy (anonymous):
you solve for the y and then you solve for the x
