Susan wants to learn more about how temperature changes in her city. She creates a table that shows the low temperatures for two days. The table is below. Which of the following statements is correct? Day Temperature 1 -8° 2 -3° The slope between the data points is positive because two negatives makes a positive. The slope between the two data points is negative because the temperature decreased from Day 1 to Day 2. The slope between the two data points is positive because the temperature increased from Day 1 to Day 2. The slope between the two data points is negative because the two temperatures are negative.
