A slope also known as the gradient of a line is a number. The correct option is A, C, and D.
<h3>What is Slope?</h3>A slope is also known as the gradient of a line is a number that helps to know both the direction and the steepness of the line.
For the given question,
- The temperature increased until 4:00 p.m.
This can be observed in the graph, as the slope of the graph before 4 pm is positive, it can be concluded that the temperature is increased until 4 pm.
- The temperature decreased after 6:00 p.m.
This can be observed in the graph, as the slope of the graph after 4 pm is negative, it can be concluded that the temperature is decreasing after 4 pm.
- The temperature increased more quickly between 12:00 p.m. and 4:00 p.m. than before 12:00 p.m.
This can be probed by calculating the slope of the line between the two points. Therefore, the slope between 8 am to 12 pm will be 1, while the slope from 12 pm to 4 pm will be equal to 4/3.
Hence, the correct option is A, C, and D.
