Linear Equations and Graphs

The Graph of a Linear Function (Drawing a Graph Using 2 Points)

There is a unique line that passes through any two given points. Hence to draw the line given by a function, you need only to:

• calculate two points that satisfy the equation
• join the two points by a line (and extend it as far as you wish).

Example 2.

Click on "New Example" to view an example of drawing a line given by a function. The line will be drawn on the graph below. Each time you click "New Example" a new example will be shown.
