1) In a linear relationship, both the dependent and independent variables change. In a linear relationship the dependent variable usually increases. For example, if you were raising money for a walk-a-thon, the amount of money you have will increase. If you go 10 dollars per hour, there would be a constant rate of 10. When the dependent variable goes up the independent variable goes up. In the example I just gave you, hours would be the independent variable. The hours would increase as time goes on. In conclusion, when the dependent variable goes up the independent variable goes up.

2) The pattern of change is how much something goes up by. In a table you can't see the pattern of change but it is there. The pattern of change is how much each number goes up or down by in the column. For example, if in one column it goes 2, 4, 6, the pattern of change would be 2 because you are just adding 2 to each number. It has to be a constant rate to make it linear. In a graph the pattern of change is how much each dot in the graph goes up by. If the dot is increasing by 6's than the pattern of change is 6. In a equation, the pattern of change is the rate. For example, if the equation is D=8.5H the 8.5 would be the pattern of change because that is what you are multiplying the H by. In conclusion, the pattern of change how much each number decreases or increases by.
