• Proportional is Not a difference it is a Relationship between numbers for ex. 1 is 20 2 30 4 40 so it is times 10 you see?
• A relationship is called proportional if and only if the ratio of y to x is constant. This means that whenever x is multiplied by a factor, y is multiplied by the same factor. Graphically, this means that the relationship is represented by a straight line that passes through the origin.

• how would i do this on a bigger graph in the thousands
• There are two ways to scale a graph, instead of going by 0, 1, 2, 3 (and negatives to the left or down), the scale can be changed to 0, 1000, 2000, 3000, etc, including negatives without even having to change the size of the graph. The other option is to define each of the x and y axis in terms of larger numbers such as x represents dollars (in thousands).
