Enter any 2 line equations, and the calculator will determine the following:

* Are the lines parallel?

* Are the lines perpendicular

* Do the lines intersect at some point, and if so, which point?

* Is the system of equations dependent, independent, or inconsistent

- Lines are parallel when they have the same slope.
- Lines are perpendicular when they have slopes which are negative reciprocals.
- For a line y = mx + b, m is the slope
