What is the circumference of a circle with a diameter of 2 feet? Use 3.14 for pi.

A 5.14 ft
B. 6.28 ft
C. 3.14 ft
D. 12.56 ft

Explanation:

Pick any two rows from the table to plug into the slope formula.

I'll pick the rows where every value is positive (rows 3 and 4)

Using the slope formula, we get the following:

m = (y2-y1)/(x2-x1)

m = (1-5)/(2-1)

m = -4/1

m = -4 is the slope and it's the rate of change

For any linear function, the slope and rate of change are the same thing.
