C1 Coordinate Geometry
- Equation of a line given gradient:
- Equation of gradient:
- A: (2,4) B: (6,8) m= (8-4)/(6-2), m=1
- A: (2,4) B: (6,8) m= (8-4)/(6-2), m=1
- Parallel and Perpendicular:
- Parallel Line - M1 = M2
- y=4x+5 is parallel to y=4x-3
- y=4x+5 is parallel to y=4x-3
- Perpendicular Line - M1 x M2 = -1
- y=-4x+12 is perpendicular to y=1/4x+3
- y=-4x+12 is perpendicular to y=1/4x+3
- Parallel Line - M1 = M2
- Equation for midpoint of a line:
- A: (1,-1) B: (1,5) MP= (1+1)/2 , (-1+5)/2 = (1,2)
- A: (1,-1) B: (1,5) MP= (1+1)/2 , (-1+5)/2 = (1,2)
- Equation for length of a line:
