Which line fits the data best? A line of best fit runs close to the points — it need not pass through any of them.
Minutes of exercise (x) against resting heart rate (y) x = 1, y = 67 x = 2, y = 65 x = 3, y = 63 x = 4, y = 61 x = 5, y = 56 x = 6, y = 55
- y = 73
- y = 3x + 73
- y = −3x + 73
- y = −9x + 73
