- We are given two points:
The gradient of the line is
- We are told a point on the line and the gradient of the line.
- We are told two perpendicular lines meet at a given point or
a given value ofGiven
the equation of one of the lines, find the equation of the other
line.
The y – coordinate ofis
The gradient of the line is -2 so the gradient of the perpendicular line is
- We are told a line is parallel to some given line and passes
through some point.
Since the lines are parallel the gradient
