Higher - The gradients of two perpendicular lines will always multiply to make –1. Make sure you are familiar with finding the equation of a line and calculating gradient to understand equations of ...

A perpendicular bisector is a line segment that is perpendicular to another line segment and passes through its midpoint. In geometry, it is often used to construct angles, triangles, and circles.

In this case both the slope and the y intercept are known and the equation can be written directly. For example if the slope is -2 and the y intercept is (0,6), then the equation is In this case the ...
