Find the equation of a line that is perpendicular to a given lineand passes through the point. |
|
Answer» For a given straight line ax + by + c = 0, and given point (u, v), the equation of a line perpendicular to the given line and passing through the point is bx - ay + bu - av = 0. Straightlines are a very important topic one must understand in order to do well in coordinate geometry. They are used to graphically represent linear equations and fin their applications in various fields related toengineering and science. For understanding them, we first need to understand how an equation is represented by a straight line, and how to deal with perpendicular lines. |
