The temperature at 5:30 a.m. was –4° Fahrenheit (F). Eight hours later, at 2:30 p.m., the temperature is the opposite of –4 °F.
The number line shows numbers from negative 8 to 8 in intervals of 1. The point A on negative 8, the point B is on negative 4, the point C is on 0, the point D is on 4.
Which point on the number line shows the temperature at 2:30 p.m.?
Point D (4)
To find the point on the number line that shows the temperature at 2:30 p.m., we need to determine the opposite of -4°F.
The opposite of a number is the number with the same magnitude but opposite sign. In this case, the opposite of -4°F is 4°F.
Looking at the number line, we can see that the point representing 4 is denoted as D. Therefore, point D on the number line shows the temperature at 2:30 p.m.
To determine which point on the number line corresponds to the temperature at 2:30 p.m., we need to find the opposite of -4 °F.
The opposite of a number is the number that, when added to the original number, gives a sum of zero.
Since the opposite of -4 °F will give us zero, we need to find the point on the number line that is zero.
From the information given, we can conclude that the point C on the number line, which is at 0, shows the temperature at 2:30 p.m.
