A line is a function that can be written in the following form:

In particular: graphically, a line is a function whose inclination constant at all

points.

1. Elements of a line equation

The slope, represented by the letter m, measures the inclination of the line. It

corresponds to the variation of the value of y when x increases by one unit.

Graphically, it represents the vertical variation of the line for a horizontal move

of one positive unit.

If the line passes by the points

and

), the slope is obtained by the

relation

∆

The Y‐intercept, represented by the letter , is the value of when is zero. It is

the position of the line when it crosses the y‐axis.
