1 markAn object is travelling backwards in a straight line, with a constant speed of 2 m s-1. At t = 0 s, the displacement of the object is 3 m.
By taking forward motion as positive, which statement best describes the displacement-time graph of the object?
A straight line with a gradient of 2 which intercepts the x-axis at 3 s
A curved line which intercepts the y-axis at 3 m
A straight line with a gradient of - 2 which intercepts the x-axis at 1.5 s
A straight line with a gradient of - 2 which intercepts the origin
