A scatter plot shows that as the number of absences increases, grades usually decrease. A line of best fit shows a negative association and predicts that students with 2 absences usually earn about 90%.
Would a student with 8 absences most likely earn:
- about 95%,
- about 80%,
- or about 70%?
Explain your reasoning.
About 70%.
Reasoning: Answers vary, but something like, "The scatter plot shows a negative association, so grades tend to decrease as absences increase. Since 8 absences is four times more than 2 absences, the predicted grade should be much lower than 90%."

What is the value of x ?
Double Your Points! What knowledge of lines and triangles did you use to find the value of x ?
x=70°
Double:
1. Since straight lines add up to 180° , I knew that the missing angle had to be 180°-120°=60° .
2. I also know that the interior angles of a triangle always add up to 180° , so 50°+60°+x°=180° . x has to be 70° .
