What is the slope of the line? A. -1/7 B. 1/7 C.–1 D.1 http://static.k12.com/calms_media/media/1417000_1417500/1417242/1/78bd85d6763d76c1b7292055c9bcc3f181e566e1/MS_PA_130905_170048.jpg

I think it's D

OpenStudy (linn99123):

ԅ(≖‿≖ԅ) oh really now?

OpenStudy (anonymous):

I got C

OpenStudy (anonymous):

I think so I'm not sure

OpenStudy (anonymous):

The answers C

OpenStudy (anonymous):

Use The Slope Formula \[m= \frac{ y_{2}-y_{1}}{ x_{2} - x_{1} }\]

OpenStudy (linn99123):

Were did u get thos formulas D:

OpenStudy (anonymous):

It's Called The Slope Formula, This Is How You Find The Slope Of The Line Lol. They Should Have Taught This To You.

OpenStudy (linn99123):

They did but i get so confused

OpenStudy (anonymous):

These Are The Coordinates (-5, 4) and (2,-3) \[x_1= -5, y_1=4, x_2=2, y_2=-3\]

OpenStudy (anonymous):

Now We Plug Those In The Slope Formula \[m=\frac{ -3-4 }{ 2+5 }\] \[m=\frac{ -7 }{ 7 }\] \[m=-1\]

OpenStudy (anonymous):

So The Answer Is C ☺ All You Have To Do To Find The Slope Of A Line Is Plug In The Given Coordinate Into The Slope Formula

Good job explaining:)
