The slope of the line would be zero (or, it is a horizontal line). The reason is, the ratio of the circumference to the diameter is constant for all circles. (More accurately it is pi, not really 22/7.)

If one were to graph an equation y = circumference/diameter, the slope would be zero because the ratio of the circumference to the diameter is constant (not exactly 22/7 since it is an approximation of pi).
