Jewelry
A graph has cord length (inches) on the x-axis and number of beads on the y-axis. A trend line has a regression equation of y = 2.52 x + 1.61.

Angelique has a cord that is 32 inches long. Based on the information above, which is the best estimate for the number of beads she can use?
A.12
B.68
C.82
D.132

Answer 1

My estimate would be C.

Answer 2

Answer: 82

Y=2.52x + 1.61

32 is going to be your x value

Y= 2.52(32) + 1.61
Y= 80.64 + 1.61
Y= 82.25

Round Y to 82
