1. As a dependant variable changes, the independent variable changes as well. The independent variable depends on the dependant, when the independent changes so does the dependant. For example, if you had money as a dependant variable and distance in miles as the independent variable, the distance in miles would increase as the money went up. When you graph these the dependant variable goes on the y axis and your independent variable goes on the x axis.

2. The pattern of change shows up in a graph if the line or points are in a straight line. This means that there is a constant rate. A linear relationship shows up in a graph if the numbers increase at a steady rate.

example

1 $5
2 $10
3 $15
4 $20
5 $25

as the distance increases by one the money increases by 5 dollars. That means it increases at a constant rate.
