The temperature two days ago is represented by the point (-2, x) where x is the temperature. Since the temperature yesterday was right in between today's temperature and the temperature two days ago, the temperature yesterday would be the average of the two temperatures.
Average = (0 + x) / 2
Average = x / 2
Since x is the temperature two days ago, x = -2°.
Therefore, the temperature yesterday would be the average of 0° and -2°:
Average = (0 + (-2)) / 2
Average = -2 / 2
Average = -1
So, the temperature yesterday was -1°C.
Alex is tracking temperatures. Today the temperature was 0° Celsius, which is represented by the point (0, 0) . If the temperature yesterday was right in between today’s temperature and the temperature two days ago, what was the temperature yesterday?
