an "extended object" is in balance when the center of mass is located directly over the fulcrum. By using a test mass mT placed at various points xT on the object (as measured from some fixed reference point), a linear relationship between xT and the fulcrum location xF is found (equation 6):

m_(T)x_(T) = (M+m_(T))x_(F) - MX_(CM)

If a plot of mTxT versus xF were made from an object of M = 125 g with XCM = 4 cm, using a test mass of mT = 30 g, what would be the slope and y-intercept of the line? Your answers will need units.
