Line Graphs

r

Line graphs are usually used to show dependent data, and particularly trends over time.

Cartesian Graphs

r

Cartesian graphs compare two sets of numbers, one of which is plotted on the x-axis and one on the y-axis.

Axes

r

Graphs have two axes.x-axis(horizontal), may contain categories or numbers.y-axis(vertical), usually contains numbers.

Measurements

Height

r

Length

r

A measurement of distance.

Degree

r

A unit of measure used for angles.

Dimension
