Answer :
A line can be named using two capital letters of points on the line with a line drawn above them; using lowercase letters; or using one single lowercase letter.
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.
