Answer:
1- y= -1.25x+15.5 because you can estimate the y intercept to see that it intercepts at 15.5 and you find the slope by calculating it with the points 2,15 and 6,10.
2- it decreased approximately 1 and a half minutes a day because the slope is -1.25, or one and a half minutes lost
Step-by-step explanation:
6-2/10-15=-1.25
