a teacher graphs the number of study sessions (x) and test scores (y) and finds a line of best fit: y = 8x + 70. one student studied 4 times but scored 95. what does this tell you?

Explanation:

Step1: Calculate the predicted score

Substitute \(x = 4\) into the line - of - best - fit equation \(y=8x + 70\).

$$y=8\times4 + 70=32 + 70 = 78$$

Step2: Compare the predicted score with the actual score

The predicted score is \(y = 78\), and the actual score is \(y = 85\). Since \(85>78\).

Answer:

The student scored higher than predicted.
