1. Find the slope of the line by counting the change in y and the change in x. (Remember, slope is rise over run).

OpenStudy (anonymous):

Read from left to right. Looking at the left dot and then the right dot, how much does y change? (down is negative, up is positive)

OpenStudy (anonymous):

-7

OpenStudy (anonymous):

yes. and how much does x change?

OpenStudy (anonymous):

note: if you read from left to right, your change in x will ALWAYS be positive

OpenStudy (anonymous):

2

OpenStudy (anonymous):

yes. oops...the change in y should actually be -6. i think you just counted wrong so the slope is -6 / 2 which simplifies to -3

OpenStudy (anonymous):

nice explaining BangkokGarrett :)

OpenStudy (anonymous):

yep I rechecked it was -6

OpenStudy (anonymous):

thank you.

OpenStudy (anonymous):

wait.....isn't it -6/1 ?

OpenStudy (anonymous):

yikes! you're correct! the change in x is 1.

OpenStudy (anonymous):

I missed that the first time I looked...lol

OpenStudy (anonymous):

so sorry for going too fast!.....here, have my medal back! lol

OpenStudy (anonymous):

I thought it would be 2?

OpenStudy (anonymous):

your only moving over to the right 1 space

OpenStudy (anonymous):

your coming down (making it negative) 6 spaces and going to the right 1 space

OpenStudy (anonymous):

making your slope -6

OpenStudy (anonymous):

oh okay I see now.
