Question 382687: " The circumference C of a circle varies directly with the length of the radius r. When the circumference is 8 pie, the radius is four."
this how i figured the probem
y=kx K IS THE CONSTANT
C=kr
8 pie=k(4) divided by four
2 pie=k
C= 2 pie r

A pedestrian bridge is to be built over railroad tracks running through a town. The bridge will be perpendicular to the tracks and the middle of the bridge will be directly above the tracks. If the town is represented on a coordinate grid, the tracks are a straight line running through (1, -7) and (4, -1), with one end of the bridge at (-11, 4).
What are the coordinates of the other end of the bridge?
