what is the difference between a linear and a line graph??????

A linear graph is a model of a straight line on the X and Y axis. It represents the equation y=mx+b. A liner graph has a slope. A liner graph cannot be equaled to 0.

A **line chart** or **line graph** is a type of graph, which displays information as a series of data points connected by straight line segments. It is a basic type ofchart common in many fields. It is an extension of a scatter graph, and is created by connecting a series of points that represent individual measurements with line segments. A line chart is often used to visualize a trend in data over intervals of time – a time series – thus the line is often drawn chronologically.
