Part 1 -The two graphs below represent two objects travelling along a straight path in the positive/negative direction.
Assume that the object begins at the origin in both graphs. Below the graphs are descriptions that fit either one
graph, both graphs, or neither graph. Place a check mark on the line under each graph if the statement is true for
that graph.
