PLEASE HELP ILL GIVE 40 POINTS Why might the measured radii and circumferences not be exactly proportional?

Because it goes through the origin and the line is straight but there is still the empty space between the 4 and 6.

Step-by-step explanation:

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
