The slope of a graph represents that rate of change of the variables that were plotted. The rate of change of the velocity as a funciton of time while the cart was rolling freely is the acceleration. The sign of this is important because it tells us whether the object's accleration is forward or backwards. The slopes are different throughout the class because the angles of our inclines are different. The greater the slope of the incline the greater the slope of the the value of the slope. The y-intercept of the regression equation is equal to the intial velocity and the end is equal to the velocity.
