Kendra is speeding along the highway and is stopped by a police officer. the office gives her a ticket and then she continues on her way. Graph the time on the horizontal axis and the speed on the vertical axis?

assume she was initially traveling at a constant speed. She slows down and comes to stop for a short time, then speed up then reaches a constant speed again. The graph should look like this
________ ................... ...... ___________
..................\....... ................../
...................\ ......................./
....................\ _________/ ... 0 speed here

You are looking to show you understand the differences in time. Time will go on the x axis and speed on the y axis.
So at the start she is speeding along the highway - constant high speed (maybe minor changes but say bumping along at around 80mph - or something OVER the legal limit there.
She gets stopped by the police officer - you need an abrupt deceleration - i.e. at the point she gets pulled over your you have a steep decline from the constant 80 mph to zero. It is not a horizontal line because you can't stop instantly at that speed - but pretty quick.
She spends a bit of time with the police officer while he writes her ticket - speed stays constant at zero.
Then she goes on her way - acceleration back to a constant - but this time probably one within the law (I don't know what it is in the US - it would be 70mph here in the UK). Again a fairly fast acceleration but not a vertical line - despite most car adverts claims drivers do not actually go from 0-60 in 4 seconds in normal circumstances.
Basically the graph is showing speed against time - so the gradient of the line will give the acceleration (acceleration=speed/time). If speed is constant there is zero acceleration and the line is horizontal.

They want you to put the time on the X axis(which runs left to right), and the speed on the y axis (this runs up and down).
To keep horizontal and vertical straight think of it this way.
Look over the horizon of a ship out to the ocean. As far as you can see left and right ocean.
Vertucal it runs North and South.

The dots on the graph would (starting in the bottom left hand corner) go upwards towards the top right hand corner but after a few dots, there would be a few in a straight line (ex: ***) After this they would continue going diagonally upwards.

well the graph will have to show her stopped, and then a distinct slowing down

you need to make a chart kinda like this,
S |________
P |..................|
E |...................|......____
E |....................|....|...
D |.....................|..|...
....|__________|______
TIME
ignore the "....."'s i had to use them so it would keep its shape, but you can see her speeding, slowing down quickly to stop and then driving off again at the speed limit, label your time axis with headings relating to being pulled over driving off etc, and label the top of the speed one as speeding, and the bottom stopped

Lots of luck on this word processor.
