Drawing Linear Graphs

What is Drawing Linear Graphs?

The process of converting a linear equation into an accurately ruled straight line on a coordinate grid, either by tabulating at least two correct points and plotting them to within half a small square, or by finding the two axis intercepts. A linear equation is one in which x and y appear only to the first power, so its graph is always a straight line; the vertical line x = k is the one case that cannot be written in the form y = mx + c.

This definition is part of the Coordinate Geometry chapter in Cambridge O Level Mathematics (Syllabus D).
