Two objects are moving along separate linear paths where each path is described by postion, 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 postion of the first object with respect to time is d=2.5t+2.2. The graph of the the position of the second object is a parallel line passing through (t=0,d=1). What is the equation of the second graph.
Linear equation: d = m t + b If the graph of the position of the second object is parallel to d = 2.5 t +2.2, than m = 2.5 t = 0, d = 1 1 = 2.5 · 0 + b b = 1 Answer: A ) d = 2.5 t + 1
