Solution
Solution Steps
Step 1: Locate the relevant point on the x-axis
We are asked to estimate the test score for someone who slept 1 hour. We locate 1 on the horizontal axis (Hours of Sleep).
Step 2: Find the corresponding point on the line of best fit
We draw a vertical line upwards from 1 on the x-axis until it intersects the line of best fit.
Step 3: Find the corresponding y-value
From the point of intersection, we draw a horizontal line to the y-axis (Score on Test). The horizontal line intersects the y-axis at approximately 35.
