For this case we will describe three different ways of naming a line.

Way 1:

If we have the following points:

P = (x1, y1)

Q = (x2, y2)

Points where the line passes, then we have the name of the line is:

Line PQ

Way 2:

Suppose we have:

m: slope of the line

b: cutting point with the y axis.

The equation of the line is:

f (x) = mx + b

The name of the line will be:

Lineal funtion

Way 3:

Another name of the line, we can obtain it using the definition:

line = Continuous succession of points.
