OpenStudy (anonymous):

-1, 5

OpenStudy (bbb911):

isn't y2-y1 and x2-x1?

OpenStudy (anonymous):

its just the second y minus the first y over the second x minus the first x

OpenStudy (anonymous):

Right. \[Slope ={{y_2-y_1}\over{x_2 - x_1}}\]

OpenStudy (anonymous):

yes.... or you could draw it out on a gaph ... like how many units it gos up over how many units it goes over

OpenStudy (anonymous):

So plug in your values, what do you get?

OpenStudy (anonymous):

it goes down 1 and to the right 5

OpenStudy (anonymous):

therefor -1 over 5
