Question

practice making predictions.
use the trend line for the data in the scatterplot to make
a prediction. about how many pounds were lost per
month with 4 hours of weekly aerobic activity?
3 pounds
4.5 pounds
6 pounds
7.5 pounds

Explanation:

Step1: Locate \(x = 4\) on the scatter - plot

On the \(x\) - axis (weekly aerobic activity), find the value \(x = 4\).

Step2: Follow the vertical line to the trend line

Draw a vertical line from \(x = 4\) up to the trend line.

Step3: Follow the horizontal line to the \(y\) - axis

From the point where the vertical line intersects the trend line, draw a horizontal line to the \(y\) - axis (monthly weight loss).

Answer:

Looking at the trend line, when \(x = 4\) (4 hours of weekly aerobic activity), the corresponding \(y\) - value (monthly weight loss) is approximately \(4.5\) pounds. So the answer is 4.5 pounds.
