The equation of a line calculator

A calculator for calculating line formulas on a plane can calculate: a straight line formula, a line slope, a point of intersection with the Y axis, a parallel line formula and a perpendicular line formula. To do this, you need to enter the coordinates of the first and second points in the corresponding fields.
