Question

based on the scatter plot below, which is a better prediction for y when x = 55? 34 87

Explanation:

Step1: Observe the scatter - plot trend

As $x$ increases from left to right, $y$ generally decreases.

Step2: Locate $x = 55$

The value $x = 55$ is between $x = 40$ and $x = 60$.

Step3: Estimate $y$ value

Based on the downward - trend of the scatter - plot, when $x = 55$, the $y$ value is likely to be around 34 rather than 87.

Answer:

34
