Bobby walked into a room. There was no light in the room. In the graph it shows that it started at 0, that means there was no light. Bobby then got scared and turned the light all the way up. It takes a short amount of time to flick a switch so that is why the line is more vertical than the way down. Bobby thought that the light was too bright so he slowly slid the slider light switch so he could find the right brightness. He was sliding the light slowly so the graph shows it being more horizontal. He was moving down in a slow steady rate. Then Bobby left the light at dim because it was not too dark, not too bright. In the graph it shows that it has a straight line at where it is dim. There is a straight line because it shows that the time is still going when the dim light is on. Bobby left the light dim.
