Question

an complete define for unique, infinite and no solution​

Answer 1

Answer:

Linear equation in two variable: An equation in the form ax + by + c = 0, where a, b and c are real numbers, and a and b are not both zero (a2 + b2 ≠ 0), is called a linear equation in two variables x and y.

Solution of a linear equation in two variables: Every solution of the equation is a point on the line representing it.

Each solution (x, y) of a linear equation in two variables, ax + by + c = 0, corresponds to a point on the line representing the equation, and vice versa.

General form of pair of linear equations in two variables:

The general form for a pair of linear equations in two variables x and y is

a1x + b1y + c1 = 0 and

a2x + b2y + c2 = 0,

Where a1, b1, c1, a2, b2, c2 are all real numbers and a12 + b12 ≠ 0, a22 + b22 ≠ 0.

Geometrical representation of pair of linear equations in two variables

The geometrical representation of a linear equation in two variables is a straight line.

Pair of linear equations in two variables:

If we have two linear equations in two variables in a plane, and we draw lines representing the equations, then:
