1) A dependent variable changes as the independent variable
changes in a linear relationship when a number or a unit is
changed and the line that will be put on the graph when it is
graphed will not be straight it will have bumps.

2) The pattern of change shows up on the graph wjen the line
isnt straight, it shows up on the table when the pattern of
numbers suddenly change from going up by a certain ammount
and changes to going up by a different ammount that the other
numbers are not and the pattern shows up in the equation when
the equation doesnt work for a certain number.
