Helps you to find the distance, the slope and the equation between two points, the perpendicular distance between a point and a straight line, Collinearity of three points: (the middle-point & the End-Point coordinates), the equation of a straight line that goes through a point with a slope, transforms linear equations back and forth between standard and slope-intercept forms, generates the coordinate representation of a straight line, determines whether two straight lines are parallel or perpendicular, finds the (x) & (y) intercepts of a straight line, finds the intersection point of 2 straight lines, transform a none standard from equation into a standardized form of it. |
