A class measured the radius and circumference of various circular objects. The results are plotted on the graph.
1. Does there appear to be a proportional relationship between the radius and
circumference of a circle? Explain or show your reasoning
2. Why might the measured radii and circumferences not be exactly proportional?

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.

9 x 8 divided by (5-3)=36
