EQUATION OF A STRAIGHT LINE IN PARAMETRIC FORM

Consider a line AB makes an angle with the positive direction of x – axis and a point on the line is . Let a general point P on the line AB and the distance between P and Q is r. Draw a line QL, PM perpendicular to x-axis and draw. In a right angled […]

EQUATION OF A LINE IN INTERCEPT FORM

The equation of a line which cuts off the given intercept on both the coordinate axes is determined as follows: Let PQ be a line meeting x-axis in A and y-axis in B. Consider OA = a, and OB = b. Then, the coordinates of A and B is. The equation of line joining A […]

EQUATION OF A LINE PARALLEL TO AXES

1. The equation of line parallel to the x-axis Consider the figure as shown below The equation of a line parallel to x – axis is y = y – intercept. For example a line whose y – intercept C is y = C. 2. The equation of line parallel to the y-axis Consider the […]
