1.1. Line graph

1.1.1. Connect the dots (co-ordinates)

1.2. Pie-chart

2. What relationship does the graph show?

2.1. Inversely Proportional relationship

2.1.1. As one variable increases the other variable decreases

2.1.1.1. The time taken to do a task is inversely proportional to the number of people doing it

3. What Relationship does the graph show?

3.1. Straight line graph through the origin = Directly proportional relationship

3.1.1. examples: the more i study the better i will be prepared for a test

3.1.2. Examples: the more i excercise the fitter i will get

3.1.3. Examples: the more weights i put on the spring the bigger the extension of the spring

4. Graph looks like this:

5. Bar chart
