Useful for check math homework. Line is entered primarily by touch in Cartesian coordinate system, and related parameters of each equation are automatically updated. Solver for following line related topics:

• Slope-intercept form of line
• Line defined by point and angle
• Intercept (Segment) form of line
• General (Standard) form of line

The application shows the relationships between different form of line equation and graphical representation. Line parameters in equation can be entered by keyboard, and graph is changing appropriately. Great to understand relationship between mathematical equations and visual representation of straight line. For easier understanding, graphics elements in coordinate system are color matched with related equation parameters. Appropriate for students who learn analytic geometry. Aimed for secondary school students to get acquainted with basic elements of analytic geometry in plane. Remainder for university students.
