Hope this helps please tell if i was right or wrong
all the answers would be irrational.

notice, Papa Bear is 18inches in diameter, but radius is half that
and "edge per dollar" simply means, how much circumference per dollar

Answer : y - 1 = 1/2 (x-3)
The formula for point slope is y - y1 = m (x - x1)
M is the slope of the line. The nine and three come from the point given. I used the point (3, 1). Hope this helps !
