Two objects are moving along separate linear paths where each path is described by position, d and time, t. the variable d is measured in meters and the variable t is measured in seconds. the equation describing the graph of the position of the first object with respect to time is d=2.5t+2.2. the graph of the position of the second object is a parallel line passing through (t=0,d=0). what is the equation of the second graph?
