Alex is tracking temperature to the day the day the temperature was 0 degrees Celsius which is represented by the (0,0) if the temperature yesterday was right in between today's temperature and temperature 2 days ago what was the temperature yesterday
To determine the temperature yesterday, we need to find the midpoint between today's temperature (0,0) and the temperature two days ago.
Let's assume the temperature two days ago is represented by point A (xa, ya) and today's temperature is represented by point B (xb, yb).
Since the temperature is being tracked on a linear scale, we can find the midpoint by averaging the x-coordinates and y-coordinates of the two points.
So, if point A is (xa, ya), and point B is (xb, yb), the x-coordinate of the midpoint would be (xa + xb) / 2, and the y-coordinate would be (ya + yb) / 2.
However, the given information does not provide the temperature two days ago or any other data to calculate the temperature yesterday. Therefore, we cannot determine the temperature yesterday based on the given information.
