Question

What is a geometrical representation of linear equation

Answer 1

A linear equation can either be in one variable, two variable or three variables  or more than three variables depending on the type of coordinate system chosen.

→ Equation in one variable or two variable represents a line in two coordinate system.

→ Equation in three variable represents a line in three dimensional coordinate system.

→ Equation having more than three variables will also represents also a line ,i.e equations having n dimensions i.e n variables will also represent a line in n dimensions.
