What are three other names for line p

↔

DC

↔

DB

↔

BC

Step-by-step explanation:

To answer it, we must remember one axiom.

At least two points define a line.

Then I can call line p as (see below attached picture)

Since a line is infinite, and no thickness I can choose any two points that are elements of 'p' to represent it, just in case I don't want to represent it by a single letter of the Western Alphabet.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
