please help due soon! During an exploratory activity, a student measured the diameter and circumference of several circular objects. She recorded her data in the table below. What equation best represents this data?

Answer:
(2, 6.28) (5.3, 16.64)
(16.64-6.28)/(5.3-2.0)= 10.36/3.3= 3.14
y - 6.28 = 3.14(x - 2)
y - 6.28 = 3.14x - 6.28
y = 3.14x
