Question

based on the scatter plot below, which is a better prediction for y when x = 5?

Explanation:

Step1: Observe the scatter - plot trend

The points seem to have a positive - sloping trend. When $x = 5$, by visually estimating the position of the points' trend, we can see that the $y$ - value should be around 5 - 6.

Step2: Compare the given options

We have two options: 3 and 8. Option 3 is too low and option 8 is too high compared to the trend of the scatter - plot. A value closer to 5 - 6 is more appropriate. Among the two given options, 3 is a better prediction as 8 is far above the general trend of the data points.

Answer:
