[size=150][b][color=#1551b5]Does the table represent a proportional relationship? (Or, do the ratios [i]covary [/i]/ change together?)[/color][/b][br][br]A table shows a proportion if:[list=1][size=100][*]There is a common factor that relates the x value with the y value (in other words, if x doubles, then y also doubles).[/*][*]The points form a straight line when graphed. [/*][*]The line goes through the origin (0, 0) on the graph. [/*][/size][/list][/size]

Look at the values in the table.[br]Do the they form a proportion? Check yes or no.[br]If you need a hint, use the "Hide/Show the line" checkbox.[br][br][br]This applet was inspired by Angela Herndon[br]http://www.geogebratube.org/user/profile/id/12746
