Answer:
B. y= -1/5x + 1
Explanation:
First, I found out that the slope is moving downwards (left to right) that means that the slope is negative. So I crossed out answers C & D. Then, I looked at the slope for answer A and compared it to the graph and the shlope in the graph looks like it didn't go -5/1 (rise/run). Therefore, answer B is correct.
Hope that helps.
