Can someone please explain this problem? :(

anonymous · Answer

equation?

anonymous · Answer

No, there is a graph.... :( I think you have to make an equation looking at the graph..

anonymous · Answer

well i would need to see the graph

anonymous · Answer

I attached the graph on the first comment.

anonymous · Answer

-1

anonymous · Answer

Can you explain it to my why it's -1? :(

anonymous · Answer

looks like $(-1,7)$ is on the graph
is that right?

anonymous · Answer

and also $(-3,9)$  is on the graph
compute the slope of the line between those to points for the average rate of change

anonymous · Answer

if you know how to compute the slope, you will see that it is $-1$
if you do not, i can show you

anonymous · Answer

Can you show me so I make sure I know how to do it? Thanks!! :)

anonymous · Answer

$$\frac{9-7}{-3-(-1)}$$ is a start

anonymous · Answer

arithmetic after that 
you get 
$$\frac{2}{-2}=-1$$

anonymous · Answer

since the coordinates are (-1,7) and (-3,9) you do what satellite just said

anonymous · Answer

Okay, I get it now. Thanks you guys it was a great help! :)
