Question

5b use the line of best fit to estimate the room temperature when there are 35 people in the room.

Explanation:

Step1: Locate 35 on x - axis

Find the value of 35 on the horizontal axis representing the number of people in the room.

Step2: Read corresponding y - value

Draw a vertical line from 35 on the x - axis until it intersects the line of best fit. Then draw a horizontal line from the intersection point to the y - axis representing temperature. By visual inspection of the graph, when the number of people is 35, the corresponding temperature value on the y - axis is approximately 25°C.

Answer:

25
