| Equation of straight line |
A relation between x and y which is satisfied by co –ordinates of every point lying on a line is called the equation of straight Line .
eg : 3x+4y =5
General form of straight line is given by
ax+by+c = 0
| Equation of straight line parallel to Axes |
(1) Equation of x axis =) y =o
Equation a line parralel to x axis (or perpendicular to y-axis) distance ‘ a ‘from it =) x =a
