Coordinate Geometry

• Distance (2 coordinates) and how to use it
• Distance (between coordinate to line)
• Distance (between coordinate to line). If distance answer given, find x
• Distance (between 2 parallel line)
• Division of line segment (different ratio)
• Division of line segment (midpoint)
• Find Area (using coordinate (x,y)) [any shapes]
• If Area answer given, find unknown x
• Find Gradient (use 2 coordinates)
• Collinear, use gradient = gradient, find unknown x
• Form equation (1 coordinate, 1 gradient)
• Form equation (1 coordinate, 1 gradient use parallel or perpendicular line to find)
• Point of intersection (equation 1 equation 2, find coordinate (x,y) )
• What is Parallel and perpendicular line , and how to differentiate
• Find Locus
