Graphing proportions is to take two ratios and plot them on an (x,y) coordinate plane. You need to be consistent with your labeling. If you use the numerator of one ratio as your x coordinate, then the numerator of the other ratio must be the 2nd x coordinate. You can graph as many of these points as are given. If your ratio's are proportional then you will have a straight line. If it is not a straight line when graphed your ratios are not proportional.

TaigaStraight line graphs that go through the origin, like the one immediately below, show that the quantities on the graph are in direct proportion. This straight line graph really tells two stories. If you can say that A is directly proportional to B, then you can state that B is directly proportional to A. The above works out the same.

Can a Texas instrument graphing calculator also be used as a scientific calculator?
A Texas Instruments graphing calculator can be used as a basic calculator, a scientific calculator and a graphing calculator.
What is the difference between a scientific calculator and a graphing calculator?
A graphing calculator is a scientific calculator with a graphing display window. Otherwise, there are no limits to the type of calculations that can be made on either of them.
What is graphing method?
In systems of equations, the graphing method is solving x and y by graphing out the two equations. x and y being the coordinates of the two line's intersection.
