Each time Lorelai fills up her gas tank, she writes down the amount of gas it took to refill her tank, and the number of miles she drove between fill-ups. She makes a scatter plot of the data with miles driven on the y-axis and gallons of gas on the x-axis, and observes a very strong correlation. The slope is 35 and the y-intercept is 0.83. Do these numbers make sense, and what do they mean (besides being the slope and intercept of the line)?
