1.  Mrs. Collins made a scatterplot to show the relationship between the number of absences and a student’s final exam score. Based on this scatterplot, a student with 6 absences should get approximately what score on the final exam? 

• 65
• 92
• 70
• 76

Which set of values is a function?

• (9,5) (10,5) (9,-5) (10,-5)
• (3,4) (4,-3) (7,4) (3, 8)
• (6,-5) (7, -3) (8, -1) (9, 1)
• (2, -2) (5, 9) (5, -7) (1, 4)

f(x)=x²-2x+1
Evaluate the function for f(-1).

• f(-1)=4
• f(-1)=0
• f(-1)=2
• f(-1)=-1

find line of best fit through these points

(1,3) (2,4) (5,8)

• y=1.27x+1.615

• y=2x+7

• y=1.7x+8

Which equation matches the graph?

• y = -x - 1

• y = -1

• y = -x

• y = x - 1

Simplify the expression: 3(1 - 2x) + 7
