Alice collected 57 skipping stones. she skipped 3 stones a minute on her pond until she was out of stones. create a slope intercept equation that represents this relationship

y = 57 - 3x

Step-by-step explanation:

Alice collected 57 skipping stones. And she skipped 3 stones a minute on her pond.

So. if y represents the number of stones left to her and x represents the number of minutes, then by the condition given we can write  

y = 57 - 3x (1)

So, this is equation of a straight line in the slope-intercept form. (Answer)
