Straight Line Graphs
Formula
- y=mx±c
- m = gradient
- c = y intercept
- y=mx±c
Parallel Lines
- y=2x+1 y=2x-1
- Parallel lines always have the same gradient
Perpendicular Lines
- y=2x+1 y=(-1/2)x-3
- The gradient of a perpendicular line is the negative reciprocal of the line to which it is perpendicular
Gradient
- gradient is the difference in y / difference in x
- can be expressed as ∆Y/∆X
- gradient is the difference in y / difference in x
Y intercept
- The y intercept of a line is the point at which that line crosses the y axis
