# Point of Intersection of two Lines Calculator

An online calculator to find the point(s) of intersection of two lines given by the equations :

a x + b y = c

and

d x + e y = f .

## Intersection of two Lines

This calculator solves the system of equations, represented by the equations of the two lines above.

1 - if you enter parameters a, b, c, d, e and f such that D = a × e - b × d is not equal to zero, one point of intersection exists and is calculated and displayed.

2 - if you enter parameters a, b, c, d, e and f such that D = a × e - b × d = 0, two possible cases:

case 1) If either Dx = c × e - b × d is not equal to zero or Dy = c × e - b × d is not equal to zero, no point of intersection exists. The message "no solutions" is dispalyed.

case 2) If both Dx = c × e - b × f = 0 and Dy = a × f - c × d = 0, the two lines are equivalent and have an infinite number of points of intersection given by the graph of one of the two equations.

## How to use the calculator to Find the Intersection of two Lines?

1 - Enter parameters a, b and c, of the equation of the first line and parameters d, e and f of the equation of second line and press "enter".
