In  distance - time graphs, we plot time on the ____ and distance on the ____. 

x-axis, y-axis

The further to the right on the axis, the longer the time from the ____. (distance-time)

start

The higher up the graph, the further from the ____. (distance time)

start

If an object is at rest, a ____ is shown on a distance time graph.

horizontal line

at rest means

not moving

If an object is moving at a constant speed, it is shown by a _____ on a graph. (distance-time)

straight diagonal line

a steeper line indicates ____ (distance time)

higher speed

when a line is curved upwards, it is showing ____ (distance time)

positive acceleration

when a line is curved downwards, it is showing ______ (distance-time)

negative acceleration (deceleration)

In a speed (velocity)- time graph, we plot time on the____ and speed on the _____.

x-axis, y-axis

The further to the right on the axis, the longer the time from the _____ (speed (velocity) time graph)

start

The higher up the graph, the higher the _____ (speed/velocity time graph)

speed

If an object is at a constant speed, it is shown as a ______. (speed/velocity time)

horizontal line

In speed-time graphs, a straight line _____ mean that the object is not moving.

does not

If an object is positively accelerating, it is shown by a________ going up. (speed/velocity time)

straight diagonal line

If an object is _______, it is shown by a straight, diagonal line going down. (speed/velocity time)
