Using the points ( 0, 100) and ( 13, 0) , the slope of the line of best fit is about: ( 100 − 0) percent ( 0 − 13) hours = 100 percent − 13 hours ≈ − 7.7 percent hour. This means that the battery life remaining decreases by about 7.7. ‍. percent for every additional hour of time spent on phone. The y -intercept is about ( 0, 100) .
