Do what we did before

OpenStudy (anonymous):

pick 2 points from the table

OpenStudy (anonymous):

8-2 2-1 ?

OpenStudy (xapproachesinfinity):

slope is \[\Large m=\frac{y_2-y_1}{x_2-x_1}\]

OpenStudy (xapproachesinfinity):

take any two points in that table and use them

OpenStudy (xapproachesinfinity):

take for example (-2,8) and (-1,2)

OpenStudy (anonymous):

i did 8-2/-2-1 = 6/-3=-2

OpenStudy (anonymous):

?

OpenStudy (anonymous):

-2-(-1)

OpenStudy (anonymous):

you put -2-1 which is wrong

OpenStudy (anonymous):

so it should be 8-2/-2-(-1)

OpenStudy (anonymous):

6/-1 =-6

OpenStudy (anonymous):

that's right

OpenStudy (anonymous):

thanks :)

OpenStudy (anonymous):

no problem
