Two linear equations having two same variables are called pair of linear equation in two variables. The general form of pair of linear equations is _ _ _ _ _.

• ax + by - c = 0

• ax + by + c = 1

• ax + by + c = 0

• ax - by - c = 0

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

• INTERSECTS

• PARALLEL

• TRANSVERSAL

• CORRESPONDS
